Doppelganger

Doppelganger is a 2D top-down game where you command a gunship in space. Your only view of the battlefield is a tactical radar screen. You must track targets as blips, manage your ship's power, and survive combat against enemy fleets. The game is played in an "Arcade Mode" where you earn points for defeating enemies. These points can be used to buy permanent upgrades for your ship between rounds.
