9.0 Presentation
A continuation of the launch title franchise, Resistance 2 continues the battle against the Chimera. Lack of a narrator does hamper some of the cohesiveness of the game, however.
9.0 Graphics
Resistance 2 does have some weird technical and visual glitches, but the sheer number of enemies onscreen at once adds to the feeling of a massive battle for humanity.
9.0 Sound
Otherworldly sounds coupled with great voice acting and ambient effects heighten the action of the game.
9.5 Gameplay
Single player is a great experience with an epic scale to the campaign, but adding co-op and competitive play within the game only serves to augment the overall gameplay.
9.5 Lasting Appeal
A fast paced 10 hour single player campaign with multiple unlockables and difficulty levels are matched with extra multiplayer modes, gameplay options and community features.
