Hello !
I've just joined a 1.2 server where a guy (called "enterprise Gay party" or smthng like that) was "cheating"/hacking the game :
he was flying around without using jet, only using some hacked version of the shotgun with pullback power multiplied...
Each shot would send him flying about half a screen awayn and damages were mulitplied (1 hit dead even if not in realistic mode and far from him) !!!
please investigate (if not already known and fixed)
