Kurok is a game using a heavily modified quake engine designed especially for the PSP, and later on if there is enough demand, a PC version.

It has one single player episode’s worth of content, as well as a fully functional multiplayer mode. It features some gameplay features in the style of “Turok” and “Goldeneye” on the N64, as well as its own features.
