I also noticed that I didn't disable resampling so sorry if that gives some of you guys cancer.
Fudgiebalz pointed out that before the first 2 pistol kills, I just had it sitting there and then sped up the kills. I realize I should have probably sped through the sitting still and then slow mo'd on the kills or something.

Also, I figured adding in the sound by itself but I'm not sure how to do that especially when it comes to slowing down the sounds. Would probably take more practice on working on something like that.
