bloody awesome! and in both ways, too.
the singleplayer should've let you [re]play as any of the 4 members of Delta Squad, but no worries, as this is still the goriest fun-fest of the year. you'll find yourself laughing in multiplayer even if you die, since every way to die in GoW is full of ragdoll-physics, body parts, and lots&lots of blood.
multiplayer could've had a respawn mode, but the 1-life MP rounds give it more of a tactical edge--stray away from your team, and die a bloody death almost immediately; stay with your team, and become victorious.
