Про цю гру

Team up and shoot down waves of invading aliens.

A top-secret government laboratory experiment went wrong, and now invading aliens have infested the military base.
Time to clean things up! Grab your weapon, recruit a friend, and start blasting wave after wave of alien scum into oblivion.

Obtain more powerful weapons, battle against enemies of all sizes, clear each room, and restore order to the facility.
