Like Maniac Mansion, Double Fine's The Cave will allow you to pick several characters from a roster of archetypes looking to explore a mysterious cave for their own personal quests. These characters include traditional protagonists like a knight and a scientist, but the roster is rounded out by stranger characters like a time traveler, a hillbilly, and a fairly creepy pair of twins.
Each character has their own special abilities and their own storyline that will unfold while they explore the self-described (yes, the eponymous Cave talks to you) "mysterious and sultry" caverns.
Since the game requires you to go spelunking with a custom team of three characters (though not all at once; you can switch between them at will), The Cave will support a local multiplayer option that allows friends to take over controlling the second and third characters whenever they're onscreen. If you wander off, there is no split-screen mode; The Cave will simply follow one character and drop control of the others until you come back to them or switch which character you're controlling.
Gilbert mentioned that the Double Fine development team worked hard to make these transitions seem natural and seamless, but without any hands-on time with the game it was the one part of the demo that left me more skeptical than excited.
The Cave should not be confused with Double Fine Adventure, the company's other adventure game that raised over $3 million on Kickstarter earlier this year. Double Fine Adventure is still in its infancy, while development of The Cave significantly predates Double Fine's crowd-funding campaign. During our Q&A Gilbert claimed his team has been working on The Cave for about a year; the game will be published by SEGA and is expected to release in early 2013 on Xbox Live, the PlayStation Network and the PC (presumably via Steam).
We'll have more information on the game as its release draws nigh; for now, have a look at a few more screenshots from The Cave.
