Die-hard Gun fans with itchy trigger fingers can scratch their worries away now that Activision’s revealed more information on the game’s release on PSP. The first-person shooter, which should trot into stores this fall, will be developed by Neversoft and UK-based Rebellion Studios and will feature PSP-exclusive features like extra missions, a quick play mode, and multiplayer modes (although we're unsure if GameSpot implied "modes" to mean both Ad-hoc and Infrastructure).

Gun didn’t fire off blanks when it debuted last year on all major consoles and PC, but as with all ports, we’re still hoping that the retooled control scheme and graphical scale-back don’t cripple this pony on the PSP.
