Space Crusade is a sci-fi strategy game based on the board game made by Milton Bradly that shares the same name. The game also shares similar mechanics to those found in HeroQuest. Up to three players control a team consisting of a commander and four space marines. Each level - set in floating "space hulks" - has a story and a set of mission objectives that require completing, often involving destroying a certain enemy unit or procuring an item. As in Gremlin's earlier game HeroQuest, Space Crusade also uses a turn-based system and determines to-hit and damage rolls via dice - white for light weapons, red for heavy weapons.
