Gunner

Dual Wield
It's like they say two is better than one, with this skill you have twice the shots of the other guy with both your guns(you only need to buy one).

Acrobat
You spend your life with speeding bullets so dodging one for you isn't that hard, neither is doing a one hand back hand spring while fireing at an enemy. You're an Acrobat baby!

Scatter Shot
Release Multiple shots at once to turn your enemies into swiss cheese.

Cannon Blast
How you fit a bullet of that calliber in that gun I'll never know but now you can bombard your enemies with large bullets like cannon, just lookout for that kickback

Rain of Terror
A single shot straight into the air burts into thousands of shots raining down to hit your enemies spot on while avoiding your allies and innocents, how the heck do you do it?
