Todd Tries... Space Marine Adventures!

About Space Marine Adventures: Labyrinth of the Necrons, from BoardGameGeek:

The Necron Overlord has arisen, and he seeks to take over the galaxy! Standing between this tyrannical maniac and his ultimate prize are five Space Marine heroes - mighty battle-brothers who have sworn to halt his evil plans. Space Marine Adventures is a fast-paced cooperative game for 1-4 players, pitting a squad of brave Space Marine warriors against the menace of the alien Overlord and his robotic footsoldiers in the dark and dangerous labyrinth of the Necrons. There are three levels to complete, each offering a different challenge. In order to win a game you must successfully fulfill the mission objective for a level. Advance rules and challenge cards allow you to tailor the difficulty of each level, and all three levels can be combined into a single campaign - the true test of a Space Marine hero!
