Portal is a 2007 puzzle-platform game developed and published by Valve. It was released in a bundle, The Orange Box, for Windows, Xbox 360 and PlayStation 3, and has been since ported to other systems, including Mac OS X, Linux, and Android (via Nvidia Shield).

Portal 2 looked nice on integrated graphics, even on medium settings.

With Valve running the show behind Steam, the online game store most popular amongst PC gamers, there is literally no need for them to make a third title of Half-Life 2, Left for Dead 2, or Portal 2.

While some people will fly right through Portal 2 because they’ve played the original or perhaps are just very smart, others will undoubtedly find it frustratingly hard, but only at times. With that said, the difficulty level in Portal 2 is very well-balanced.

You can play Portal 2 without having played Portal first as every game mechanic is presented in Portal 2. However, you’ll spoil the story of the first one doing that as it is a direct sequel (and there are many references to the first one, in the story and in some puzzle).

Valve Software launched their much anticipated first person action/puzzle game today. This represents a simultaneous Mac launch alongside Windows, Playstation 3, and Xbox 360 releases. Portal 2 is available through Valve’s Steam online store as well as through traditional retailers.

Portal 2 has online cooperative support, but both people need to own the game.

There have been many complaints about the length of Portal 2 but, like many of the complaints leveled at the game, they’re mostly unfounded. The single-player game can take six to 10 hours to play, and the co-op campaign is at least five hours long.

Like the original Portal (2007), players solve puzzles by placing portals and teleporting between them. Portal 2 adds features including tractor beams, lasers, light bridges, and paint-like gels that alter player movement or allow portals to be placed on any surface….

Steam won’t allow shared accounts to play the same game library at the same time — even if you’re playing different games, two people can’t play from a single library at the same time.

There is no way to “move” paid games between accounts, though. If you bought a game on one account, you can set it up for sharing via the Steam Family Sharing feature, but it won’t be registered to any other accounts except yours.

Family Sharing allows family members to share games while keeping their accounts separate. Family and guests can play one another’s games while earning their own Steam achievements and saving their own game progress to the Steam Cloud. It works by granting family members access to games on a shared computer.

Yes, you can share your games with your family. Steam recently introduced Family Sharing, a system where a user can share his library with the rest of the family and others who use the same computer. You simply need to enable Family Sharing on the computer you want to use: Log in with the account you want to play with.

If you want to play on another PS4 that isn’t your primary console, you can download any game you’ve bought on the PS Store as long as you sign into PSN. You do not have to connect to the Internet or pay any usage fees to play used games.”
