DOOM 3: BFG Edition

Simply beat Doom 3 RoE on Veteran difficulty. Remember to save often and if you feel you could of came out of a fight with more health just reload and retry cause that little extra health goes a long way if you play right. Also good thing to remember that the double barrel shot gun is a 1 hit kill on almost all monsters if your close enough, as well as the grabber is a 1 hit kill on small monsters so you can save your amo with this. Also don't forget to use the artifact lots it can get you out of many tight spots.
