Space Crusade is a turn based 1 to 3 player strategic game where players take control of a Space marine Squad. The AI is acting for the aliens. After choosing a mission, the marines must be equipped and orders have to be chosen. The higher the rank of the commander, the higher the amount of orders he can give in battle. The commander is the most important figure of your squad. He can gain higher ranks by completing missions which will, in turn, allow more orders to be given out, and will also allow him to carry more equipment. All three commanders can be saved after completing a mission.
