Games like Apolune

Apolune is a minimalist, endless procedural evolutionary space war. Enjoy fighting wave after wave of enemy starships in a classic "2D" simulation that evolves and mutates as you fight on, victorious. Defend the Earth from hordes of vile aliens in your simple craft: point-and-shoot. Attach a second keyboard or share elbow-to-elbow in the action with friends and family.
