About this app
The Galactic Space Agency has hired you, one of the 3 marshals, to stop the alien invasion. Don't let the alien swarm xenomorph into a huge galactic empire. Hunt the drones, attack intruder hives and destroy the alien colony. Only you can defeat those pesky pirate spaceships! Crush their defences or all humans will end up abducted, dead or turned into centipede. Zerdian is a 2d twin stick shooter - you move with the left stick and shoot with the right stick. No geometry here - you fight real spaceships. You fly a piece of junk at first - don't worry - you'll get some cool new weaponry in no time. So gear up and get into the battle now! Features: - 2d twin stick shooter gameplay, like in Geometry Wars - Upgrades - Cool retro music - Leaderboards - Achievements - Game replays - Lots of cosmic battles and exploding alien ships
