"Now, four months after release, Crytek is happy with the state of Crysis 2's online multiplayer.
Crytek recently released a DirectX 11 patch for the PC version of the game, which allows those with powerful computers to ramp up the graphics.

But the developer promised to dip back into support of the game if a hack emerges that demands attention. "
