Gunpey , released for the PlayStation Portable in 2006 , is a puzzle game that challenges players to create an unbroken line from left to right by moving segments up and down. The game features an abstract theme, with extra skins unlocked through play.
The PSP version includes various game modes such as Challenge mode, single skin and double skin modes, 10x10 mode, quick start, time attack, and a two-player wireless mode. Two different rule sets are also included: original and break, which automatically drops segments down if a line is formed below them.
