It looks like they've balanced the game so that you don't have to do the glory kills now, which is good. My opinions are probably skewed since it was staged and they probably had it on a low difficulty setting.
And it is more or less base Doom, I'll admit.
Modded content is generally very frantic.
Being that the maps are so large and open though, they really do need to overhaul the AI and up their speed, awareness, give them the same mobility as the player to skate around the map and be a real threat, rather than just a bullet sponge.
