This is a strategy game in which players attempt to save Earth from an alien invasion. From a ¾-top-down perspective, players manage resources, engage in combat missions, rescue characters, and terrorize alien installations. Players use rifles, machine guns, pistols, and grenades to kill enemies (e.g., human-, insect-, beast-like characters) in turn-based combat. Attack moves occur in brief cutscenes that depict characters getting shot or wounded/killed by explosions. Splashes and pools of yellow and red blood sometimes appear when characters are injured or killed. During the course of the game, players can customize soldiers with accessories, including lit cigarettes and cigars.
