Epic Games was working with PS3 and they ported Gears of War 3 to PS3 just with a technical interest as an engine test. The code for this game was used in exchange for different goodies in a different level for some years, but there was a problem: the game did not work. PixelButts was able to do it work, and now, the same person has released the game.
You can download this rarity from here, but only works in a PS3 Devkit, due to the retail machine has not enough RAM to run it. In the future, the game should be executable in RPCS3 emulator.
What a moment to be alive.
