Portal 2: Infinity will be a fully voiced single player campaign, which takes place a few years after the end of portal 1.

But when the Portal Transit, the system that links together the facility, is hacked while you're testing; it's up to you to find out what's going on.
Somewhat like a one way deal
So it's like an incandescent particle field that you can place a portal on. Neat!
Really cool concept!
You should place two portals on it and show us what happens.
