I played this as a multiplayer campaign with my friend. It was very engaging and fun for the most part, with the different vehicles, weapons, enemy types, and challenges constantly keeping the playthrough fresh. That is, until Mission 7 where the latter half of the game isn't as sharply designed, with long repetitive sections of shooting through groups of enemies in a hall or simply retreading an old level. Plus, the Flood enemies can sometimes feel a bit too damage-sponge-y and take really long to take down.

The feeling of the earlier levels, the story, and the high of racing to the end in the Warthog was such a blast though, that I need to give this game credit for it. I'd recommend playing this with a friend, undoubtedly.
