From GameBrew

Last Updated2011/09/13

CSPSP is a homebrew game for the Sony PSP, originally based on Valve's popular Counter-Strike. It's a 2d overhead (top-down) shooter that features team and free-for-all gameplay with a variety of weapons, all within a fully functional multiplayer component.

It was participated in the Neo Summer Coding Compo 2006 (PSP Games) and Neo Spring Coding Compo 2007 (PSP Games, 3rd place).

Note: The homebrew was later updated by UnLuck3R with 3DS-PSP-PSVita Crossplay and the project is continued by MasterMan (see CSPSP+).


  • Completely free of charge.
  • A total of 28 different weapons to take down enemies with, including knives, pistols, submachine guns, rifles, machine guns, and grenades.
  • A quickly growing multiplayer community (there's almost always someone to play online).
  • A user account system with simple stats and friend lists.
  • Hundreds of different maps.
  • Fully-featured map editor (by coolguy5678) for the PC.
  • Readily moddable (graphics, sound effects, gun configurations).


CSPSP should run on any of the recent Custom Firmwares.

For most cases, simply copy the CSPSP folder into /PSP/GAME/ on your PSP's Memory Stick (or /PSP/GAMEXXX/, where XXX is your Firmware version).
