AWM sucks on the contrary, random 1 hit KO chance, theres only 3 versions of g36 which are:
-g36C (not too good)
-g36 rail (obtained from modding the above, very good gun,somewhat difficult to use)
-g36 alligator, easy as pie, no recoil, good rof, good dmg, expensive to get as its obtained from gcoin caps and is new atm so everyone wants it
PPSH could be described as OP i guess because you can spray the sht outta those 71 rounds but then again its easy to kill a PPSH user.
Id say sidewinder and alligator are OP, thats it
