It's taken more than 25 years but a NES game made by Nintendo itself will finally be coming out in North America. You may have seen or heard homages to The Mysterious Murasame Castle in Nintendo games but the real deal comes to the 3DS this week. Get ready, but this sucker looks hard.

Originally released for the Japanese Famicom system in 1986, The Mysterious Murasame Castle is a top-down action game like the early Legend of Zelda titles. (The trailer above is for the European release.) Players control a lone samurai storming multiple castles in feudal Japan, with the goal of destroying an alien presence that's sowing evil through the land. It features music from Koji Kondo, the man most famous for composing the Super Mario Bros theme.

The game's main character has showed up in cameos of other games, like Samurai Warriors 3 for the Wii and the Takamaru's Ninja Castle section of Wii U launch title Nintendo Land drew its inspiration from Mysterious Murasame Castle. Nintendo briefly showed the original game in action at Comic-Con two weeks ago and it seems like it's a super-challenging game.
