Anticube 2 - a game within a game

So, as I sometimes peruse various forums, the occasional gem pops up. This is one of the best hidden gems in Open Source gaming.

Anticube 2 is a map for Tesseract / Cube 2 that is inspired by the game Antichamber and NaissanceE. If you are unfamiliar with those, that means it is an abstract FPS puzzle game where things are not quite what they seem. Or, as the creator Lord Kv probably better explains:

Anticube 2 is a puzzle map for Tesseract. You'll find yourself in an interactive, dynamic, non-euclidean world. Supported by 5000+ lines of Cubescript and GLSL code, this map will do things no other Cube 2 / Tesseract map has ever done before.

Here is the trailer:

There is also a gallery of screenshots for you to check out. I won't include them here because, to be honest, the screenshots won't mean much for this kind of game.

I'm calling it a game, even though it is just a map for a game. You can tell it is worth checking out because of the reactions it elicits from the Tesseract developers (warning: NSFW language). Here's what developer ImNotQ009 had to say about it:

Whoa, I would NEVER have though I'd see anything like this on BARE Tesseract.
This is one hell of an astonishing piece of work, the music is great, the whole atmosphere and the aesthetics are really good as well. With the exception of a little bit lousy looking (compared to everything else) terrain on the very last part but nevertheless I genuinely couldn't stop "wow-ing" through out the whole thing.

Anyway, check it out, let us know how you get on. This definitely deserves more attention than it has gotten up until now - but then again how does this kind of thing get more eyes on it when it is just a game within a game and one which is currently suffering from a severe lack of a player base? Hopefully we can change that starting here. :)
