I never really liked death mask that much. Somehow you didn't get too much control over the game. In games like doom or even wolfenstein (The old one) you could make it harder for the enemy to hit you. Here when you encounter an enemy it seems more like you stand still facing each other while shooting away.
I noticed a multiplayer function, but I doubt it'd be much fun though. If you tried to run away you'd just end up getting shot in the back so Deathmatch is out I'm guessing since it would be a question of who gets the first shot as long as noone runs out of ammo.
