Gain Ground — About this game
Gain Ground turns each battlefield into a tactical problem. Pick a fighter, use normal shots and that character’s special weapon, and decide whether to fight or run for the exit. Rescuing trapped people expands the team available for later stages. Ordinary stages can be cleared by getting fighters out or defeating the enemies; arenas without exits demand combat. Different movement speeds and weapon ranges make the choice of fighter matter, especially as the timer runs down.
