Ok all you UK Xboxers....I need your advice.

After having played these two games, which is more enjoyable for multiplayer. Enclave boasts 1-4; Gun metal 1-2
Can you play through the entire game with multiplayer (i.e. Halo co-op, Gauntlet), or are you limited to a quasi~game (i.e. 007 A.U.F., Halo deathmatch)?

These questions aply to non-UK Xboxers also....I just figure they would know hands-on.

Thanks all!!
