It's not out yet.
no you cannot anymore because portal prelude was terminated
Unfortunately, no. Although you can download apps that give you walkthroughs, tips, etc.
you need to by the starter pack. you cant download the portal of power
The internet
go to game stop, download steam, insert disk, wait for load, click game, start awesome.
I don't believe you can because the maps are only downloadable from the Steam Workshop, not the PS Store. I hope they have a way soon but for right now it is only for PC. If you bought Portal 2 new you should have a redeem code for a free copy of Portal 2 on Steam.
1- open portal 2-go to bonus maps 3- click import bonus maps 4- go to the computer's hard drive, click PROGRAM FILES, STEAM, STEAMMAPS, (YOUR STEAM USERNAME), PORTAL, PORTAL, MAPS, then the new folder you created.
The program Steam allows you to buy it, and many other games. go to steampowered.com to download Steam, start Steam, search for Portal, hit Purchase Game, and download it
Portal or Portal 2 mods on Steam is installed by first Downloading it and extracting it. Then copy the map file into your Portal 2 maps folder which is Run the game.
Yes and Portal 2.
Portal - 2002 Portal 2-21 was released on: USA: 18 November 2003
No, Portal is for PC only. Portal 2 is for PS3,Xbox 360,and PC. Plus it would suck on PSP.
