In my quest to get the dragonslayer (berserker armor already found) I came across a BFG. At first, it was just going to be storage space for energy ammo for the railgun, but then I found the firestorm pack. I figured, might as well get that mod done, and later on I found another firestorm pack. As luck would have had it, I found a nano pack shortly after that, and I gotta say that this is pretty fun.
So unless the floor has a valuable item on it, what I'd do is fire the biggest fucking gun on a crowd, fire it at another crowd, and then hold on to the period key until I recharge the thing. If anyone gets close, usually a bruiser brother or a cyberdemon, I just melee them to death. And so far, it pretty much kills the majority of the crowd. From normal archviles to barons of hell. So much fun.
