This week’s XBox Live Arcade game release fooled me with its initial screenshots into thinking it was a full-blown retail game that had slipped off my radar. But no, War World is a new addition to the Arcade, downloadable today for 800 MS Points ($10). It’s a third-person shooter based around mech combat, and it boasts 100 different levels to play through in 5 difficulty levels. Additionally you’ll have four multiplayer modes, including Capture the Flag, Bomb Assault, Deathmatch, and Team Deathmatch.
