The upcoming Donkey Kong Country Returns port for 3DS has been somewhat mysterious. We knew it would be a direct port and add stereoscopic 3D, but we weren't sure if it would have anything completely new.

A press release on Nintendo's UK site reveals that the game will in fact have new content. You can check out the full release here, but here are the highlights:

Grab the letters that spell out K-O-N-G and nab puzzle pieces hidden in each stage to unlock extra content, like super-tough Trophy levels. Unlock and conquer every one of these special stages and a brand new surprise awaits!

New mode makes the going just a little easier, giving Donkey Kong and Diddy Kong three hearts each instead of the usual two, letting them Kong-a for longer! Spend your hard-earned Banana Coins on helpful items from Cranky Kong’s shop, and pick up new items that help save you from falls, allow the Mine Cart and Rocket Barrel to take a second hit, and even let you use a DK Barrel whenever you like.

Discover brand new content created just for Nintendo 3DS.

Donkey Kong Country Returns 3D will be available for 3DS next month, May 24.
