Nothing has been announced as of May 22, 2011. But there is still one unfinished story chell's past I don't know if there is going to be a portal 3 but I sure hope so :)
SPOILERS!!!
I hope there is, but Chell's life ended nicely, her leaving. If valve really wanted a portal 3, the field chell went to could be fake, a test chamber...
Then there is ratman, Atlas and P-body, and at the end of the co-op coarse, there were alll thoes test subjects..
Please valve!!! PORTAL 3
They're making a Portal 3, so yes.
Portal 2
hepatic artery, portal vein, and common bile
Late 2013, maybe. ;)
Urm... you just buy Portal 2 from Steam and then play it...
the next valve game coming is the portal 3 half life 3 thanks for asking and have fun on the game bye for now
In the real world sadly that's impossible. In the show, there's the movie "Equestria Girls" of which Twilight travels (by portal) to another world where they are human, and there is a portal that stays open for 3 moons, back to Equestria. So in that way, yes there is that portal.
Geek Crash Course - 2011 Portal 3-7 was released on: USA: 4 January 2012
You have to find an End-Portal in a stronghold. The probablility of finding a stronghold with an End-Portal in it is small. Because there are 3 strongholds per map, and there is 1 end-portal per game.
To get into the twisted woods portal, you must: 1. Use the portal rune 2. Use the warrior portal rune on the torches from left to right. 3. Use the trixter portal rune on the blue circles in the order middle right, middle left, bottom left, bottom right, top. 4. Use the magestic portal rune on the portal itself. 5. Use the shadow portal rune on the words in this order: Restilin, Seesh, Romorsh, Antog.
