Portal 2 è un gioco in uscita dalle caratteristiche molto particolari: questo titolo sviluppato e pubblicato dalla casa Valve Corporation, difatti, si colloca a metà strada tra un puzzle-game e uno gioco di azione in prima persona. L’uscita in Europa è prevista per il 22 Aprile 2011.
Intanto il sito Xbox360Achievements ha reso noti gli obbiettivi di gioco di Portal 2, che sarà giocabile su piattaforma PC, Mac, Xbox 360 e Playstation 3.
