Binary Space: Where Did We Go?

Hi Everyone!

If you’ve been playing Class 3 Outbreak or Zombie Outbreak Simulator for a while, and keeping up with what we’re doing, you’ve probably noticed that we’ve been extremely quiet lately. The last major update on our blog was back in April, just after we released Zombie Outbreak Simulator for iOS, with a minor post at the beginning of May when we released v1.1 of ZOS for iOS with support for 10 maps. Our last post on our Facebook page was back in June, and we haven’t posted much on our forums in ages.

So what happened, and where did we go? Were we bitten by zombies? Were we kidnapped by government operatives seeking our expert knowledge on simulating potential zombie outbreaks?

Here, finally, is an update of what we’ve been up to. Followed up with a big announcement of where Binary Space is going next!

At the end of May we released Zombie Outbreak Simulator Free for iOS. By default a single map was enabled, with limited infected options. There was a single in-app purchase for $0.99 to upgrade to the full version, enabling all 10 maps and all of the options.

In June we released an update to ZOS on iOS which added the ability to drop bombs on the unsuspecting hordes (and unlucky civilians).

Bombs in ZOS for iOS

On the 11th of June 2012 at Apple’s WWDC keynote, Apple announced iOS 6. One of the major features announced was that Apple were replacing Google Maps with their own new mapping platform. We had thought this might happen at some point – there had been widespread speculation that Apple were going to replace Google Maps, since Apple had been acquiring a number of mapping-related companies.


At the time we were working on the bombs update. We finished that off and submitted it to Apple. While we were waiting for it to be reviewed, I downloaded the developer preview of XCode and iOS 6, to test ZOS.

This confirmed that Map Kit, the Apple API which ZOS was using to work with Google Maps, had switched to Apple’s own maps. I checked each of the 10 maps supported by ZOS. At the time the quality of the images at all 10 locations was worse than Google’s – ranging from “not as good as Google” to “really bad”, to even having random static at a couple of locations. Also, none of the locations were available in high enough resolution to be able to zoom in to the level at which ZOS is played. For example, here’s a comparison of how the Netherlands map looked on iOS 5, and with the developer preview of iOS 6:

ZOS for iOS Netherlands map on iOS 5

ZOS for iOS Netherlands map on iOS 6

To be fair to Apple though, their release notes did say “Map data will continue to evolve – only a limited amount of high-resolution satellite imagery is currently available”. By the time iOS 6 was due to be released (rumoured to be mid-September at that point), maybe the image quality would have been better. But we couldn’t exactly bet on that happening. Plus, even if Apple’s imagery was great, it was still different to Google’s. For the couple of maps which were recognizable, the imagery didn’t line up with the walls, trees etc that we’d edited, and which did align with the Google maps – which would have meant re-editing those maps somehow.

I tried asking Google if they were planning to release their own new native API for iOS. If they were going to release something before iOS 6 came out, maybe we could just switch over to it. Their response was “we can’t comment on what our future plans are”.

With no other options available, we figured we had to remove Map Kit, so remove the currently-Google-soon-to-be-Apple maps. Rather than leave ZOS to die when iOS 6 was released, we decided we’d buy some aerial photos, and just embed them directly in the game. We had already bought one map of Leicester England from Bluesky for the original C3O, so we bought another map from them of Coventry England. Huge thankyous to for also allowing us to use some of their aerial photos for three locations in Australia!


We tried to find some aerial photos in the US (as most of our sales of ZOS for iOS have been from the US), but we were unable to find anyone who would sell us aerial photos of a good enough quality.

Embedding the photos into the app instead of using Map Kit to download them as needed from Google increased the size of the app considerably. I didn’t want the app size to increase too much, or else it might become too large to download over the mobile network in a reasonable time. So we decided to reduce the total number of maps to five.

ZOS for iOS v1.3

We released the update in mid-September, a few days before iOS 6 was due to be released.

That was over two months ago – since then it’s been basically radio silence from us. What have we been doing?

Mostly, Jay and I have been taking a break, and having lots of discussions about what to do next.

We started porting ZOS to iOS around August last year, and that work required me to rewrite all of the code, but we were able to reuse a lot of Jay’s original artwork. So during that time Jay had much more available time than me, and so for the last year or so Jay has been working on another game by himself. I resigned from my job back in July, so I’ve been enjoying an extended holiday, spending more time with my family, which has been great! :)

In amongst this Jay and I have been discussing what to do with C3O and ZOS. Our games have been dealt a few blows recently. As I described in my last blog post, Google announced that in September 2014 they’ll be switching off the Flash API for Google Maps which we use for the web versions of C3O and ZOS on The web versions of the games will die then, unless we spend a considerable amount of time rewriting them in JavaScript. And then Apple’s release of iOS 6 forced us to remove Google Maps from ZOS on iOS. We wondered whether we should retire C3O and ZOS, and move on to something else. We spent a bit of time prototyping a different game idea, but didn’t get far.

In the end, Jay and I have decided that we’re going to split up, and go our separate ways. It’s been over three and a half years since we first started working together on C3O and ZOS, and while we’ve worked together well, we’ve come to realize that we have different ideas about the types of games we’d like to build. Jay is going to release the game he’s been working on for the last year or so under his own new company name. And Jay has agreed to let me take over Binary Space – we’ve come to an agreement where I’ll gradually buy out his share of the company over the next several years.

So what am I going to do with Binary Space?

Despite the obstacles which Google and Apple have created, I’m going to continue development of C3O and ZOS. I think the games still have potential. Despite being unfinished, our web versions at still get around 30,000 visitors a month, and have been played a total of over 3.2 million times since first release. And despite being more of a toy than a game, ZOS for iOS has been downloaded by over 100,000 people. And across them all, we’ve gained over 9,000 fans on Facebook. So, I think there are many people out there who still like these games, and I’d like to find out what I can do with them if I keep on trying! :)

Last year more smartphones were sold than PCs, with smartphone sales growing by about 60%, tablet sales growing by about 270%, and PC (desktop, notebook and netbook) sales only growing by about 2%. Although the PC is far from ‘dead’, mobile seems to be the place to be at the moment. So I’m very keen to keep developing for mobile platforms.

However, the major problem for mobile apps is ‘discovery’. With over 700,000 apps on Apple’s App Store as of September, and Google Play also hitting 700,000 apps about a month ago, it’s extremely hard for apps to get noticed. Many apps struggle to get anywhere, and the vast majority of apps probably earn very little. ZOS has done reasonably well on iOS, with over $20k of sales from over 100,000 downloads since we released in April. I think the main reason is that we already had a lot of people playing our web-based games, which we could promote the iOS version of ZOS to.

So what I’m planning is a two-pronged approach: continuing to develop both the mobile and web-based versions of our games. While we’ve earned some revenue from ZOS on iOS, we’ve earned very little from the web-based versions of C3O and ZOS. So by continuing to develop for mobile I hope to continue earning revenue to help support Binary Space. And by continuing to develop the web version of C3O I hope to keep up a steady stream of players who might be interested in buying the mobile version.

One thing I want to do is build a stronger link between the web and mobile versions. There are about 2000 maps featured on the front page of, but the iOS version of ZOS only has 5 maps. What I’d like to do is make it possible for the iOS version of ZOS to play all of those maps which are available on This was something that I always wanted to do with ZOS on iOS, right back from when we first started working on it, but we decided to start small and just support a single map at first. After the initial launch we decided to take it in stages, first increasing that to 10 maps. I had hoped to eventually extend that further.

The removal of Google Maps from iOS 6 put a dent in these plans. However I’d like to keep trying to get it to work. There is no official Google Maps API for iOS any more, but it is possible to use Google Map’s JavaScript API in a web app on iOS. What I’m hoping is that I can build some kind of hybrid web-and-native version of ZOS for iOS, which will allow it to use Google Maps again. This will probably be tricky – this was one of the approaches which I originally experimented with and discarded because it was too slow, back when I was first trying to get ZOS to work on iOS. However I have some more ideas that I’m going to try. I think it will be worthwhile if I can pull it off, as it will allow the games to build off each other – people playing the web version can make more maps for mobile players to play, and people playing the mobile version will have a reason to play the web version if they want to make a new map.

After that I’d like to keep adding further updates to ZOS on iOS, to help keep it interesting. However it will probably always remain as a kind of ‘toy’, just an amusing LOLfest to pass a bit of time :) In the longer term I’d like to also release Class 3 Outbreak on iOS, to bring some actual gameplay with controllable units to iOS, but that will be a fair way in the future.

At some point I’d also like to try producing an Android version of ZOS. Since announcing that we were building ZOS for iOS, we’ve had a number of people ask for an Android version. I’m not sure if this will be possible – as I’ve found on iOS, getting thousands of zombies roaming around over a map at a decent speed is tricky. Google does have an official Google Maps API for Android, but it doesn’t support satellite images without labels, which is what ZOS needs. Ironically, the current version of ZOS on iOS (with just 5 embedded aerial photos) should be able to be ported to Android without much problem, as there is no mapping to worry about. So I will probably start with that, and then see how it goes from there. When I ported ZOS to iOS, I wrote most of it with fairly standard C++ and OpenGL ES, with a relatively thin layer of iOS-specific Objective C at the front end, to interface with the maps and the iOS UI. The C++ and OpenGL ES back end should be able to work on Android too, so it should be less work to port ZOS to Android than it was to port it to iOS the first time. However it still won’t be a small amount of work, so it will be a while before I’ll have time to start experimenting with this. One of the reasons we initially started on iOS before Android was because the general opinion is that apps usually earn more on iOS. This article from a year ago found that iOS apps earned about 4 times as much as Android apps, although this more recent article from a couple of months ago suggests iOS may only be about 50% higher than Android. The only way to find out what ZOS could do on Android will be to try it! :)

Then there’s the web version of C3O. It’s been forever since we last released an update for it – way back in August last year when we added shotguns. I’m going to start working on updates for the web version again, and the first things I plan to do are centred around giving map editors more control over their maps. At the moment all games use the same infection settings, which were tuned by Jay to feel okay for an ‘average’ suburban map (and the settings can only be changed in ZOS). The first thing I want to do is give the map author the ability to choose the default infection settings, so that you can choose what makes sense for your map.

Currently your starting group of survivors always starts right in the middle of the map, which was just the easiest thing to develop first. Instead I’d like to add the option for you to choose the spawn point for your survivors.

At the moment the game has no objective – you start with some survivors, and have to try to avoid the zombies, but otherwise there’s nothing in particular to do. I’d like to add the ability for the map author to choose an objective. Over time I’d like to add several different objectives which you can choose from, with the ability to change the relevant parameters. For example these might be to survive for X minutes, or to get to location X, or to rescue person X from location Y, and so on.

I’d also like to extend the game from being about a single map each time, so map authors can create a ‘campaign’ across multiple maps. So you could create a collection of maps where once you complete the objective on one map, you can progress onto the next map. Eventually you might also be able to carry your team of survivors from one map to the next.

On top of these kind of editor controls, the actual gameplay itself could do with some more features, like the ability to find and use more kinds of weapons and equipment, equipping your team, forming survivors into squads, building defences, survivor skills, and so on. Maybe there will be other types of people you can find to help your group of survivors – like police or military.

At the moment you need to play out an entire game in a single session. As the game gets more complicated I’ll need to add in some kind of way to save your progress, so you have a persistent game stored on the web site, and you can drop in to the site to play for a few minutes (or longer :) ) whenever you like. Perhaps you’ll have a home base which you can gradually build up over time, adding fortifications while you continue to scavenge for supplies and recruit new survivors. Eventually it would be awesome if there could be some kind of cooperative multiplayer, maybe even make it somewhat MMO-like, so each map has its own set of persistent fortifications.

However, I’m only one person. All of the above will take a lot of work, and I’ll be adjusting priorities as I go, based on what seems like the best idea at the time, and based on the feedback I get from you.

Adding more features to the web version of C3O will hopefully help in advertising the mobile version of ZOS to more people, and it will hopefully help make more maps for mobile players to enjoy. However another benefit of working on the web version of C3O is so that I can try out various gameplay ideas, which I could eventually make use of in a mobile version of C3O. This is why a mobile version of C3O is probably a fair way off yet.

Originally, Jay and I planned to turn the web-based version of C3O into a free-to-play game – we mentioned this back when we launched our crowd-funding campaign. So you would have been able to play the game for free, but have the option of spending real money for extra in-game items if you wanted to. In the long term this may still happen, but it’s not my immediate focus. There are a number of challenges around this, not least of which is that Google won’t allow me to charge for a website which uses Google Maps, without paying them a hefty ($10k+) fee first. My goal isn’t to squeeze every dollar I can out of C3O and ZOS, but the more I can earn, the more I can put back into developing the games. If I do introduce any free-to-play style features, I’ll want to do it in a way which isn’t sleazy, like many of the free-to-play games out there which essentially make you stop playing until you spend some money.

As I mentioned earlier, I’m currently taking a break from work, spending time with my family. I set aside some money from my savings to cover me for about 6 months, so I’ll be returning to full time work around the end of January. That means that from now I’ve got about 2 months, where I’m hoping to be able to get a bit of a head-start on developing some of the above features for C3O and ZOS on iOS. After that I’ll be back to developing C3O and ZOS in my spare time around my work and family, so the pace will be slower, like how I developed the games in the past.

Since it’s been so long since I did anything on the web version of C3O, I’m going to focus on releasing an update to that first – ie the ability for the map author to change the infection settings. After that I’ll switch to working on both the web and mobile versions in parallel – maybe a couple of days on one, then a couple of days on the other. I’ll see how it goes – it may be easier to concentrate on a single feature on one platform at a time.

The web versions of C3O have about 2 years left to live – before Google will switch off their Flash API for Google Maps. I’m guessing it might take me around 6 months to rewrite the game in JavaScript. I’ve done a quick prototype in JavaScript, with 4000 sprites roaming around a Google map, so I know it’s possible to get it to work. However, there’s a lot of code to convert – even though the ActionScript language used by Flash is based on JavaScript, they’re still quite different. So from now I guess I have around 18 months to improve the web version of C3O. The challenge I’ve set for the next 18 months is to prove to myself that it’s worth rewriting the game in JavaScript. I’m hoping that the features I’m planning to add to the web and mobile versions of C3O will grow them both enough, to make it worthwhile to keep C3O alive after the Flash API dies. At the moment the web versions of C3O are seeing about 30,000 unique visitors a month. If the changes I make can grow that figure significantly, and if people are still playing and asking for more, then I’ll have a reason to begin the big job of rewriting C3O. It will be fun trying, anyway! :)

Jay and I worked together pretty well most of the time, and our skills complemented each other. I did the programming, and Jay did the artwork, game design, sound, music, and many other things. I’m definitely not an artist, as I’ve demonstrated in the past :) When working with Jay, I could just make things ugly, and rely on Jay to make it look good. I will now have to put in some more effort myself – but mostly I’ll be hiring freelancers to help me with the artwork, and everything else. This will be a very different way of working, and it will be interesting to see how that works out :)

I’m also planning on doing things a bit more transparently than we did in the past – so discussing what I’m working on and what I’m planning to work on, posting more on the blog, on Facebook, and on the forums. As well as being not much of an artist, I’m not much of a game designer. Jay did most of the game design (and he is a huge zombie fan), so he mostly came up with the ideas (and then I disagreed with him..). Instead, I’ll be mostly relying on your comments and feedback, for ideas on what I should work on next. While I can’t guarantee to implement everything you ask for (there’s only one of me!), I’d generally like to involve the community more, and work towards building the kind of game which you would like to see!

I’m looking forward to this next chapter of Binary Space, and I’m hoping I can produce something which you will all enjoy playing. I’ve enjoyed working on C3O and ZOS over the last 3.5 years, and what I’ve enjoyed the most is hearing everyone’s comments – and it’s because of you all that I want to keep working on it. I’d like to know what you think, so please let me know your thoughts on the forums, on the Facebook page, or in the comments below. Thanks! :)



  1. Jonathon Koontz says:

    Saxon, I’ve been a fan of yours and Jay’s work since C3O came out. Back when you only had around 200+ followers on facebook. I’m currently writing a survival horror book and I am looking to publish it sometime next year. If you are ever looking for some ideas as of storyline goes please don’t hesitate to contact me.

  2. Duhya says:

    Best of luck to you, and to Jay as well of course.

  3. Josh says:

    Thank you so much! I’ve been a huge fan since the beginning, and I honestly love this game. Please don’t let it die.

  4. Julian says:

    So, If you can drop bombs in The iOS version of the game, Could you put that in the Game Class 3 outbreak? It would be awesome for an uptade

  5. Saxon says:

    Thanks Jonathon, Duhya and Josh :)

    Julian, C3O is currently more focused on surviving as a small group of civs, so a full-on rts-style military simulation involving dropping bombs probably wouldn’t suit? But I’m planning on making it so that maps can have configurable objectives – maybe in the future one of the objectives could be to find a soldier somewhere on the map, and then use them to order an air strike of a strategic location, or something along those lines. The web version of C3O still includes a “watch simulation” option though (like ZOS on iOS), so maybe I could introduce the LOLfest of dropping bombs to that at some point, too :)

  6. Nathan says:

    I was wondering why it was really quiet in the zombie front. Glad your back Saxon

  7. Julian says:

    Wow, So in the future you’re planning make soldiers and all the thing? Awesome, And, you should read lot of things that some guys posted in the game you published in Kongregate, they ask about the same thing, But it’s going to be awesome if you add soldiers and things alike, And, In the C3O, there should be a 3rd gun, you know, a, machinegun, i dont know, a m4a1, or a Uzi, Whatever you choose friend. And thanks for replying to my question. Good luck, and keep making awesome zombie games
