Quirky developer Double Fine, responsible for the likes of Stacking, Brutal Legend and Costume Quest, has unveiled The Cave.

Developed by Monkey Island creator Ron Gilbert, SEGA will publish the title on XBLA, PSN and PC in early 2013.

The game will have you forming a team of three adventurers and exploring the aforementioned cave, which contains both a subterranean amusement park and a medieval castle equipped with a nuclear ICBM missile. Sounds like Blackpool, if you ask me.

"The concept of The Cave has been bouncing around in my head for many, many years, and then the little voices that tell me to do things said it was time to make the game," said Gilbert. Let's hope it's better than Deathspank, Ron.

"As SEGA continues to expand our digital gaming catalog, we've put a lot of effort into finding truly original experiences we can help bring to life," said Haruki Satomi, senior vice president of digital business at SEGA.

"If you enjoy rappelling, spelunking and dark rocky caverns then be prepared to be disappointed! And then intrigued. And then AMAZED. And then disappointed again, but only for a minute. Then relieved, amused, bewildered, excited, and satisfied. In that order," added SEGA's press release.

Gilbert has been teasing his new project since joining Double Fine in 2010. Before this unveiling he recently teased the project with a few bits of concept art.
