Chillingo and US-based game developer 6ixset studios today announced the immediate availability of their definitive iPhone Boxing game, Touch KO on Apple App Store. Touch KO is a 3D realistic boxing game that gives gamers a chance to advance through a boxing career, starting from humble beginnings in a run-down gym, all the way to the glamorous grand arena for the title fight. The game features an impressive control scheme, intense character customization, unique multi-touch and accelerometer capabilities of the device, and a whole slew of upgrades to buy for your boxer.

Touch KO is the only boxing game on the iPhone were you can completely customize your 3D fighter. You can choose from a variety of different boxer models and different tattoo overlays for each of them. Once finished you’re treated to a tutorial that explains the controls. The movement of your boxer will be handled with your left and right thumbs. Taps, swipes, and holds will result in jabs, hooks, uppercuts, blocks, and the like.

And then, you’re off to start your career in the ring. Before each match you can choose what areas your character will train in to increase his statistics. Winning matches will earn you cash which you can use to buy new equipment and clothing.

The game randomly generates tougher and tougher opponents as you rise through the ranks in career mode -- the number of possibilities is pretty staggering. The actual number you’ll fight from amateur up to winning the final title fight will depend upon the player’s skill and career choices. Each fight along with some cash, gives you bonuses for winning. Each time you choose a new fight, you are given a few options of different contracts to sign. Once you have earned enough popularity, you get a shot at challenging the champ in your current tier to win his title and move into the next tier. You also get a change of scenery and soundtrack as you move along.

Designing Touch KO for the iPhone and iPod touch from the ground up has kept the game from getting mired down in technical or control issues the way that a lot of ported products can be. The advanced engine technology powering this game doesn’t exist in a lot of console or PC titles. Thanks to the team at Unity Technologies, 6ixset studios really pushed this iPhone platform to places it hasn’t been before and believe that the game can stand toe-to-toe with PSP or PS2 titles.

Touch K.O. available now for $2.99 from the App Store on iPhone and iPod touch or at www.itunes.com/appstore.
