I just finished doom3 with sikkmod and I really enjoyed it. during the sale I had picked it up with resurrection of evil. So now that Im done with doom 3, I went to move on to Ressurection of Evil with sikkmodd but Im having some issues with the imps. I played doom 3 on both marine and veteran difficulties (eventually setting on marine), but in both cases if I ran up to an imp with a shotgun and pulled the trigger there was a very good chance that imp was vaporized. However in ROE, its taking like 5 or 6 upclose shotgun blasts to put them down, on marine difficulty. The other monsters seem fine, they seem to die at the appropriate level.
