Octo Tank

The Octo Tank is a tank that upgrades from the Quad Tank, Twin Flank, Triple Shot and Double Twin. It further upgrades to the Auto Octo Tank, Sede Tank, Overocto, Octo Sniper, Octo Machine Gun, Octo Twin, and the X Hustler. It fires in 8 directions, and is pretty good for farming and dealing with crowds. Still weak against Bullet Spammers, though, because it only fires 1-2 bullets in the direction it is pointing.
