Playing on Ultra-Violence is uber-cool !
However, it seems the only actually useful weapon is double shotgun.
On easier difficulties you can get away with using chaingun, but on Ultra-Violence you cant, coz the amount of monsters is huge, and chaingun only shoots at one monster at a time. Sometimes two. And some shots will miss anyway. Plasma rifle is better, but still only one monster at a time, and cells are RARE !
And double shotgun will kill whole rooms of small fry with one shot, and tougher monsters can be herded together and killed in a pack, all at once. Not only that, it will auto-reload itself just for a small cost of 3 traits (and on Ultra-Violence you will probably get the third trait at the second map !!! and there will still be someone left to kill.)
What is left...BFG, well, i cant quite understand how it works. Once i sent a shot in a big hall full of cacodemons, right in the center, the one in the very center was almost dead, the ones near the walls were wounded, but the ones in between center and the walls were unhurt.
And rocket launcher is a must for when the wall needs demolishing, or sniping someone from a great distance, but not as a main weapon.
Any comments ?
