PORTAL

http://www.joystiq.com/2006/07/18/first-trailer-of-valves-portal-released/

I just found this AWESOME new game that Valve is working on. Called Portal, its basically about portals. So you can put portals in different places and travel between them. Essentially that is a powerful weapon. The video below shows the different situations you could use portals in, and the dangers of getting in a loop =).

I am definitely buying this game when it comes out.
