The forward roll was definitely THE thing that No Remorse lacked. The lack of it often got me into trouble since I played No Regret first, so the forward roll was kinda standard issue to me. On No Regret mode, I hardly used anything but rolls to keep low so the shotgun would fire faster. Alas, in No Remorse I either had to crouch forward or roll sideways and hope I turned quick enough in case an enemy appeared in front of me. Ah the good old days.
