"Visually, the 'heavily modified' Doom 3 engine looks to the untrained eye very much like Doom 3, although with outdoor areas and busier action it should prove more interesting. And in a nod to the risible situation in Doom 3 (that resulted in the unofficial gaffer tape patch) you should now be able to hold a gun and a torch at the same time. A number of classic weapons will return, and all will be modifiable, enabling you to steer a rocket launcher or bounce a railgun, for instance. Naturally, id is also promising a 'kick-ass multiplayer component,' with 16 players, grenade jumps and all that, plus some classic maps with very much a Quake III feel."
