DAWNOFWARII: RETRIBUTION (M)
★★★★ Fans of real-time strategy games or the Warhammer 40,000 universe would do well to check out this stand-alone expansion pack. In addition to the Space Marines, players can choose from five other factions. Each is unique, so the campaign has plenty of replayability. Multiplayer is solid, too, with a great new cooperative mode called Last Stand, where players fight against waves of enemies.
