Mega patch 3640 has arrived! New stuff includes support for DirectInput controllers, keyboard remapping, "friends only" online matches, HUD improvements for better gameplay feedback, and lots of new shortcuts! We've also fixed random slowdowns in online multiplayer, reduced slipperyness on some Transporter maps, prevented unfair deaths due to online lag, made many HUD/UX improvements, and improved game stability and performance across the board.
