Alien Invasion is an action shooter where you defend Earth from endless alien waves and blast your way to safety with slick weapons and quick moves.
In Alien Invasion, use WASD or the arrow keys to move. Aim and shoot with the mouse or touch. Destroy each wave before your shields drop. Collect power ups and spend coins on weapon upgrades between rounds to keep the pressure on in this endless fight.
Tip Focus fire on the toughest targets first and pick up damage boosts as soon as they appear.
