I'd say, it depends on the type of game...
For a top-down game, I'd be a pretty tough, high damage BeerTent with either a really big sword, or something similar to Dedede's Rocket-Hammer. I might not be the fastest, and I'd occasionally heal myself by taking a drink (Also would be my weak-point.) Firearms wouldn't work so well either, as I'd have a shield I'd quickly put up to protect myself from danger. Occasionally, I'd pop in a status effect, but this would only get prominent if I ran low of health, and can't find a safe spot for a breather in the arena.
For an FPS... Hrmmmm... I'll take from Brink on this one, as i'd be a lot faster, and with firearms instead of the sword. I'd be quick to slide into cover, and probably end up taking a few shots to whittle down the player as I quickly speed in-between cover. I'd require either quick reflexes or traps to put me down, either that or a melee character to take me by surprise Either that or make it a race. If you get to the booze before me, You'd win, as... Well... I'd just be a Tent without the alcohol.
