The default, basic as basic gets. 3 shots. For boring people or those who haven't played arena. So, boring people.

Turns an enemy to your side. Affected enemies must still be killed to proceed. 2 shots. For the manipulative weirdos.

A personal favorite. Only 1 shot, but fills incredibly quickly. For those who hate getting punched while sampling.

At a glance, the same as the Colonel, but has x2 healing for allies, and cannot trigger berserk mode. 3 shots. For all those mom types out there.

Amps up punches to the maximum. Adds gore explosion. 2 shots. Use if you like a mess.

Rose Kennedy gone wrong. After a delay, enemies you stick will explode. 2 shots. Still for the messy ones.

Teleports you to nearest enemy on strike. 2 shots. For those who gotta go fast. (Or aren't picking Nat for some reason)

A runner-up to Purple Rain. Heals slightly while in berserk mode. 1 shot. For those with anger management issues.

Gives access to a dash (Dodge and punch, counterpart to the slide) that neatly seperates enemies' heads from their bodies. How convenient. Only works for 1 enemy in a group. Will knock the rest over. 1 shot. For those who don't know the Y button exists.
(For some reason it didn't want to work in arena, so Prison it is)

A solid 3rd place. Instead of exiting berserk mode upon performing a fatality, the duration will extend. 1 shot. For button mashers.

Drains health, but puts you in a constant state of a lesser berserk mode. (All bonuses are slightly reduced.) Obviously, cannot trigger berserk mode, can only heal. For the simple minded.
