Monster Hunter Generations Ultimate will release for Nintendo Switch soon, and now Capcom has dropped some news on Twitter via the game's account. It's releasing a free, playable demo of the game on August 16, where you'll get the chance to try all six Hunting Styles and new Prowler abilities. [Update: The demo is now live on the Eshop.]

The full game will release on Switch on August 28, but 3DS players may be very familiar with it. Monster Hunter Generations Ultimate is an expanded version of the original Monster Hunter Generations, which came out on 3DS in 2015. It includes more content, including two new Hunting Styles (Alchemy and Valor), an additional Elder Dragon, and a new endgame boss. You'll also be able to go on "G Rank" quests identified as "even more formidable versions of familiar foes." The game has already been out in Japan for some time under the name Monster Hunter XX.
