Alien Front Online gives gamers the option to choose their fate. Aliens have invaded Earth and taken out all air forces with their destructive orbiting motherships, and it's time to choose sides. Gamers can enlist in the army and take control of powerful tanks, using advanced weaponry to protect highly destructible cityscapes and countrysides. However, gamers with an evil streak can chose to play as the enemy, joining their three-eyed brethren to blast humans from either an anti-gravity Hov Craft, or from the heart of a two or four-legged bio-mech. Whether players decide to control the aliens or soldiers, the game's land-marking voice-chat feature allows them to converse with their comrades in order to create real-time strategies and conquer the enemy.
