Gears of War 2 is really good! Played through about 1/4 of the single-player and it's a billion times more solid/fun than the first one. Played some multiplayer last night, and it was fun, but the people I played with were kinda lame. They've got a 5-player co-op mode called "Horde" where you basically try to survive 50 waves of enemies. We got to about lvl 15 and that was hard as hell. We tried to jump into level 19 to try it and that shit was impossible. On "casual" difficulty at that.

Something I didn't know, the voice actor of the main character also does the voice of Bender, ha. Pretty cool.
