the best weapon is the mind. i mean, creating weapons only with your willpower would be awesome.
back to the topic:
an armored suit with two machine guns, a rocket launher, a shock shield, a flame shield, a spiked-ball-mode, mini-drones with lazers, lazer eyes and a dartthrower with paralyzing darts. dont forget the jet pack and the lazers on the back. oh, and a shock wave device (emp).
My favorite video game weapon was a shark gun from this bizarre third person shooter I used to play. it would launch sharks into the ground, which would then eat your enemies.
Was that game armed and dangerous? And my favorite weapon would be poppy gun. It was from a game and it would unleash bugs and it would eat anything or turn it into slime. t was very useful for creating an extra passage way.
Probably one of the lesser-known future weapons... It's a turret..... Dual-barelled DRACO-style AA turret. Preferably Flak or AP slug rounds. Not sure where I saw this.... I fink it was a lesser-known foriegn game.... Not really sure. It's 10-11mm, not sure. My favorite sword would be a Vibro-blade.
