This expansion for the RTS title Warhammer 40,000: Dawn of War II finds gamers commanding the knowledge-seeking Blood Ravens as they explore a long-lost ice planet and protect the Aurelia sector from the crusading Black Legion space marines. The expansion offers players the chance to equip extremely powerful items that may corrupt them into opposing the interests of the Emperor, while the single-player campaign finds gamers improving their gear and abilities, and advancing their squads to level 30 in 15 new single-player missions. Multiplayer additions include the ability to play as Chaos Space Marines, new units for the Space Marine, Eldar, Ork, and Tyranid armies, and seven new ice-planet PvP maps. ~ Christopher Brown, All Game Guide
