Modders have brought Counter-Strike-style gameplay to the Sony PSP with a new open-source project called OpenStrike.
This isn’t a port of Valve’s Counter-Strike, it’s a clean-room recreation built from scratch that captures the classic gameplay while avoiding Valve’s copyrighted code and assets.
OpenStrike runs at the PSP’s native 480×272 resolution and achieves a locked 60 FPS on original PSP hardware.
It is currently a single-player project with bots and round-based matches, Multiplayer is still in development.
