best weapon i have ever seen?
remember quake II? and the rockets?
yea that doesnt come close to the hyper blaster xD that gun shredded. 20 health per shot. 3 rounds/sec and 200 ammo. it was the most epic shredding gun.
BUT: most powerful weapon?
without a doubt its the Armageddon option in worms world party.
big open map with HUGE landmasses gets turned into small rubble islands with just 1 of these. you will be lucky if even 1 worm is left on the field, let alone alive.
also another fun weapon is the baseball bat when you hit people over the water in worms
WHEEEEE and you get the home run sound xD
but the overall weapon of mass killing with highest accuracy? Pistol from halo 1 OR the Scrin's warships and carriers on C&C 3 o.O
