OK so my Goto 2nd weapon to perk up while im using another perk, for some time, has been the m79 for demo. now Ive gone from lvl2 -lvl4 using mostly the m79 and yet have to have the Blooper Reel Achievement. Are the nades turning the Zed into Mist/ redsauce or Giblets. Do I need to be Demo? if no, and it is Gibs then this is a bug. if not I will continue to use the m79 forEVER. not that achievements are a big thing but its something I noticed that I should have.
