I just stumbled upon this, and i haven't seen it posted here.

An open source fps with multiplayer, and in-game map constructing/editing. This looks really impressive IMHO, Watch the video before judging ;)

Looks pretty interesting. Reminds me of Halo with map editing lol

Would give it a try once is polished. Looks pretty close already

All I am thinking is that the stole the name from the Mcguffin used in the Avengers movie ;)

This looks cool. When i read the thread's title i thought it had something to do with Avengers.

Hmmm..?

I haven't watched Avengers yet or know anything of the plot, maybe i should pick it up sometime x)

Best superhero movie of all time, will not be disappointed if you do watch :)

Aww...and here I was thinking this thread had something to do with Madeline L'Engle's "Wrinkle in Time" series...

I suspect the name came from being a fork of Cube since a tesseract is a mathematical object also sometimes called hypercube. It has been used frequently in SciFi long before the Avengers movie.

Ah, derived from Sauerbraten; that was quite a cool free multiplayer FPS!

P.s: about Avengers, well, it had great action sequences and effects, but the story.. ugh..
I don't read comics, however, maybe that's all canon..
