Beast Boxing 3D is in the Punch-Out!! mould of boxing games, which I can't get enough of. It stands out for a few reasons.
It oozes style. The "story" is the tried-and-true Rocky/Little Mac trope - a puny fighter pummels his way through an onslaught of wacky and progressively more difficult fighters - but the combatants are monsters. Mixed with a slick 2D/3D animation style, it simply looks better than most of the other boxing games around.
The simple game mechanics are well-worn - dodge, punch, don't get worn out or beaten into the ground - but the controls are nicely designed for a touchscreen, a straightforward palette of taps and swipes, while you tilt to dodge.
The major thing that's missing is multiplayer, but even as a solo campaign, if you're at all a fan of the Punch-Out!! genre, it's worth considering plunking down $US3. [iTunes]
