You are surrounded by 300 Spartans and can have two pieces of modern day equipment...

[sketch_zeppelin]

a bottle of lube and a pair of ass less chaps because i'm about to get screwed

 

[MetalGenocide]

1. A toxin tractor from C&C Generals.
2. Sound system with appropriate large speakers, playing "Winter Wrap Up".

 

[Trolldor]

A gun. Mounted on a tiger.

 

[Russian_Assassin]

301 kilos of marijuana. Then we'd order pizza or something and play GTA IV on the PS3.

 

[NnyTheV]

An Xbox360 and a copy of Halo 3. Show them what they could be under my leadership!

 

[Derek_the_Dodo]

1. A big bag of KFC
2. some pepsi as well of course

 

[Aphex Demon]

A GravGun and an explosive barrel.

The blue GravGun, to be specific.

..."Hello Mr Spartan, why that's a heavy lookin' shield you got there?"

 

[Pifflestick]

A Les Paul guitar and an amp. Shock and awe them into submission with an epic guitar solo.

 

[Zay-el]

A lighter and my phone.

Behold the shaman!

Thanks to you, my decision is definitely 2 flintlock rifles. Tiro Finale FTW!

 

[Sprinal]

An IS-7 class heavy tank.
With the natural fuel and ammo (with an instruction manuel translated to English)
This would solve all my problems.

For the non-serious one.

a Diamond pick-axe to dig a trench of 2*x*3 [where x is the width of the entire vallye] to prevent anyone getting to me. After all not even creepers can get through that.

 

[Neoseek]

I would have to go with a Mass Brainwashing device and a cloaking device

 

[Griffolion]

The Iron Man Suit and a beard. Zeus has just come to earth people.

 

[Ledan]

A computer that still somehow has access to our modern day internet, and that is solar powered. Then: a fully equipped modern tank.
Use tank to deal with immediate threat, use computer to take over the ancient world.

 

[Alon Shechter]

an iPod playing "Friday".
I am going to die doing it, but fuck it, i'm taking them with me!

Edit: Wait, wait, I got a better one!
MONOCLE SMILE!

 

[Valiant The Gamer]

an iPod playing "Friday".
I am going to die doing it, but fuck it, i'm taking them with me!

I would choose that + a iron man suit.

HAHAHAHAHAHA!

 

[AlohaJo]

A few sets of D&D dice and enough character sheets and pencils to go around. If that fails, then a gun (which has Desert Eagle, point five-oh, written down the side) in my right hand, and a katana in my left.

 

[Druss the Legend]

Flamethrower and a Cigar.

 

[Nami nom noms]

Real life weapon? probably some kind of assault rifle... they'd be helpless.
Fantasy weapons? gimme a keyblade

 

[toastmaster2k8]

Marine and his rifle, we will have them beat in 3 hours.
