A downloadable game for Windows, macOS, and Linux

Early alpha of cyberpunk FPS Ctesiphon.

Not many changes since the last Demo Day, I've been spending the last month playing too many games instead of making them, however I have passed a major milestone: From this point forward there will not be any major new code additions.

I've reached a point where virtually everything left to add is art assets: enemies, weapons, levels, maybe some cutscenes, etc. So the only big coding tasks left will be tweaking and polishing the AI and some optimization passes at the very end.

Changes since last demo day:

  • Enemies can move around and attack again (Though they tend to get confused easily when you're out of their line of sight)
  • There are now a pair of big locked doors in the level that need a keycard to open
  • Explosion effects have been changed to look a little more consistent with the rest of the game

Install instructions

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.

I'm currently figuring out how to do a Linux launcher with packr, should be able to have one ready in time for the end of submission.

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!

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.
