Assassin's Creed: Revelations..........

"greek fire" that band is named after it.. It wasn't much of a flame thrower, though.. More of a waxy aflame projectile.

Actually, the romans did use it as a flame thrower by using a sort of pull to fill chamber with fluid, push to eject fluid, with a small flame on the end. Quite a fuck awesome weapon. look in methods of deployment.

Woah! didn't know that. that's pretty scary and just adds onto how bad ass Rome was.

Yay for history!
