City Siege 2: Resort Siege is a mission-based shooting platform game. Choose up to five units to take into each mission and control them individually as you try to eliminate the bad guys in the area. Rescue civilians and collect stars along the way. Between missions, you can upgrade your units with the stars that you collect and purchase additional units with your money. Keep an eye on your soldiers' health bars; if a soldier dies in combat, he's gone for good.
