1) Shock Rifle (Shock combo's are awsome) 2) M4 in Counter Strike Source 3) Silenced Hardballers in Hitman 4
hate that gun , like it in real life but in cod4 its overated i use the ak-47 or the m16 and the .50 cal sniper
the harkonen cannon from hellsing is my current fav. iz big >=) for an idea on how big it should be: you didn't say it had to be feasible or real weapons
