A downloadable game for Windows and Linux

Early alpha of sci-fi FPS Ctesiphon.

Back from the dead yet again. This time I give you the fully rebuilt demo, completely in C++. The game should run fully reliably without crashes or stuttering. If you've played a previous demo you may want to go to the Controls menu and make sure your bindings are correct as there have been some minor format changes so certain bindings might not load.

Progress is currently focused on making a reliable editor for quickly designing and building levels. Once the editor is complete I'll work on getting some actual content into the game so it takes more than two minutes to finish. And for those curious: the editor will release with the final game and I will add support for launching custom maps.

Check out my Tumblr for semi-regular updates and past progress:


I'm also now active (sort of) on Twitter:

Install instructions

The new builds are straightforward to execute, just download, unzip and run either Ctesiphon.exe for Windows, or ./Ctesiphon for Linux

Instructions for Old Builds:

The Windows .zip version just needs to be unzipped, and then you can run the exe inside. This version comes bundled with a Java jre (from ojdkbuilds on github) so you shouldn't need Java installed to run it.

The .jar version requires Java Runtime to run. It should be sufficient to simply open the jar file with Java, otherwise you will need to open a cmd/terminal, navigate to the file and run it with: "java -jar Ctesiphon-Demo.jar" (without quotes). Linux users: Don't forget to mark the jar as executable if it doesn't work!

Awesome game, I can't wait for more, thank you for making this <3

i cant see any of the buildings, just the sky

please help

That's probably your system's version of OpenGL being too old, are you playing on Mac or Linux by chance?

I like this, clean gameplay, wacky enemies, looking forward to play it!

Great concept! Can't wait for it to be completed

This looks pretty darn fun. I'll give it a shot.

As is this is the best "unity FPS" I've ever played by far. I really liked how the guns felt, the level design and the overall style. Can't wait to play the finished thing.


Hi! here is my gameplay of the demo in a VHS style!

Great game, i can't wait to play it when more features are added


I tried this a while ago, it was kinda cool, especially the music:

Gave it a go...

Fun game! Look sensitivity is a little weird though, like the vertical look is slightly slower than horizontal. Would be OK with the difficulty being a bit higher (taking more damage and doing less) in exchange for some faster default movement speed (like CSGO does). I just like the sensation of rushing around though like you can in Hotline Miami (kinda feels like a similar vibe). Also might suggest making the atmophere a little darker, if you are trying to go for cyberpunk

Was pretty fast-paced though, was very fun to rush though. And it worked. And it was written in java of all things! Why on earth would anyone want to do code in that!

Nice work though

Thanks for playing!

I'm not sure what could be causing weird mouse behavior, it translates your desktop movement 1:01 to degress in both axes so it shouldn't be giving different sensitivities, I'll put in separate X and Y sliders if the problem doesn't go away.

I'm going to put in some more difficulty levels later that apply damage mods to the enemies, probably won't cause you to do less damage though as I think that's cheap.

Rushing around and cyberpunk are very much the idea. For now the map is really bright because I haven't put in the lighting system yet, when I do this map will be in the late evening rather than the middle of the day, and most other maps will be in the dead of night.

I want nothing more than to start again in C++, but I've come too far! If you must know, I simply found LibGDX to be very useful to get going with, after this project though I won't be touching Java again except for much smaller games.
