PS3HaX member ThatOtherPerson, who just recently released the Homebrew game Maze Generator, has released a demo of a FPS(First Person Shooter) that he is working on, here is a quote from his thread:
DownloadHere is a tech demo for a first person shooter I’m working on. Everything in it is now and will continue to be completely destructible. Use the left analog stick the move, right analog stick to aim, R1 to shoot. There is no gravity at the moment but you can use the triangle and X buttons to move up and down. There is also no set objective or challenge at this point. It really is just a pure tech demo. But I think its still pretty cool already. So have some fun digging into walls and let me know what you think of it.
