All multiplayer features including mic, other players' mics, sound effects, intense situations (lots of zombies, duh!), and running in window as opposed to fullscreen.

Every game mode, achievements.
Tested with Nvidia GeForce 9800 GT card with Driver version 185.18.36. Failed to run in wine 1.1.33, giving the incomplete installation(2) that others have encountered, but upon forcing wine to update to 1.1.43, it works flawlessly. As with other valve games, using directx 8 (-dxlevel 81) in the game's launch options improved my performance over using directx 9.
