Saw this link at another message board and thought it was pretty dope. Its like M.C. Escher made a game, haha I love the trailer.

Click me!

holy crap that is cool!
although... I doubt that I would do very good. WAY too much thinking going on for a video game for me.
:D

This looks insanely cool. I love the standalone aspect of it, like its a whole action-logic-puzzle game, just using the new portal weapon from HL2.

Imagine how crazy it will be to use the weap in a deathmatch, too. Rip a portal under the opponents' feet and then pop another one over a spike pit or something The parts on the vid where the guy opens a portal where he's falling and then pops out a wall and falls into ANOTHER portal are goddamn amazing.

Me want! That is what Prey should have had. The simplistic basic portals circa Shadow Warrior were neat, but not this neat. Certainly not ten year dev time neat either. So glad to see someone out there can creat new fun exciting shit.

This will be a truely epic expansion/sequal.

/sign me up for a portal gun IRL.
