Sentinel: Mars Defense is a strategy game in which Sentinel, the commander of the dropship, has to fight with savage aliens for survival in the earth's first off-world colony. Mars is under siege and the thousand of aliens are on the line. Organize the weapons and defenses to stop the alien in the Martian landscape. Also place walls and barriers to block the way of aliens that have different strength and weaknesses. Upgrade your weapons to repair the buildings and crop resources. There are two modes with atmospheric graphics: Assault mode where you have hours of play and Endurance mode where you can challenge other players.
