There's a circle of people around you.

[OCD1]

I would use a lasso

[General LC]

Two SMGs, duh.

[Max Headroom]

Forget weapons, they are the weapons.

[Pikagirl_777]

Some sort of sword? I dunno. Just anything that could protect really.

[NGAMER9]

A knife, as long as they have no weapons...

[ResidentZoidberg]

An Auger, from Resistance: Fall of Man. Great gun, plus can deply force fields to protect my blind sides while I'm killing them. [And you can shoot through them, of course]

If it has to be something real/realistic, then I guess a machine gun. Shotty wouldn't be quick enough.

[Cecil_and_Kain]

A pipe bomb and a mechanical pencil.

[Ragnarok]

Dual katars, steel gauntlets and a cape just for aesthetic effects 8)

[Drybones5]

Well...I'd bring my semi-portable canon  ;D

Then I'd be like a puma and shot the survivors with my M1  8)

[Kingoftherings]

Twin Scimitars.

[Mystic]

Michael Myers

[Chozo_Lord]

The Assault Rifle.

[TAINTED3]

Deadly bunnies.
Deadly bunnies are deadly. :)
