It took much longer than previously announced but today Valve revealed that they have added support via Steam for the Novint Falcon PC game controller to all of the games in Valve's Orange Box collection. That includes Half-Life 2: Episodes 1 and 2 along with Portal and Team Fortress 2 (the original Half-Life 2 already supports the Falcon controller via a patch from Novint).

The controller allows gamers to "feel" effects like weapon fire recoil, the weight of holding objects like barrels and even feel textures in the game world. Valve has promised that they will add Falcon support to their other games including Left 4 Dead.
