Cartoon Network’s Best Park in the Universe – Regular Show has just received its first ever content update.

Released just last May, Best Park in the Universe – Regular Show is a wacky fighting game based on the anything-but-regular Cartoon Network animated series “Regular Show.”

Initially, the game featured only the show’s blue jay and raccoon star duo, Mordecai and Rigby, as its playable characters. But thanks to its new update, you can now also play as the dwarfish, green-skinned fatty Mitch Sorenstein aka Muscle Man:

You asked for him, now you’ve got him! Unleash his fists of fury and pecs of punishment as he rampages through the bad guys. He comes with his own unique moves and skill tree, so it’s a whole new ball game when Muscle Man hits the field. He even comes with new achievements you can earn.

The new update also adds a fourth game world called The Resort, which contains five action-packed levels. As well, it adds a new Endless Enemies mode, which, as its name suggests, challenges you to endure wave after wave of enemies.

The new version of Best Park in the Universe – Regular Show is available now in the App Store as a free update or as a new $2.99 download. The game is compatible with iPhone, iPod touch, and iPad running iOS 5.0 or later.
