505 Games has announced Michael Phelps – Push the Limit for Kinect, due out this June.
The game is in development at UK studio Blitz Games, creator of upcoming Kinect-enabled game Yoostar 2.
It "puts you in complete control of an up-and-coming swimmer entering the exciting and gruelling world of competitive swimming, in the hope of taking down Michael Phelps," reads the official blurb.
"Push the Limit is a fun, innovative, and physical way to game that is complete with elements that will challenge serious gamers, swimmers and casual fans," said Phelps.
"I'm really excited to help bring a one-of-a-kind swimming video game to the market that is reflective of my competitive nature and passion for swimming. This definitely isn't your typical video game; much like my training in the pool, Push the Limit is about improving and mastering every race element - from controlling your adrenaline on the block to perfectly timing your finish.
"In my world, it takes a lifetime of dedication to get one-hundredth of a second ahead and I believe Push the Limit offers players a unique journey inside swimming that will challenge themselves as much as their in-game competitors."
In Career Mode, players compete in successive tournaments and travel to "some of the most breathtaking locales the sport has seen".
There are heated outdoor pools set against icy mountain ranges, a Japanese dojo and an 80,000 seat outdoor arena. Phelps guides players along the way.
From the sounds of things, you're supposed to master the action of swim strokes and learn swimming techniques, although how you do that standing up remains to be seen. Check out first screenshots and a trailer below.
