Portal 2 has been out for a few days in the US now and is officially released in Europe today. Reviews of the game have been appearing online and pretty much every one is overwhelmingly positive.
In CVG's own Portal 2 review we awarded the game 9.3, calling it "Imaginative, challenging, hilarious and sometimes a bit exhausting" and easily "one of 2011's most interesting, challenging blockbusters".
If you need further convincing of Portal's brilliance check out our early review round-up, in which OXM, Machinima, IGN, Game Informer and GiantBomb were equally as positive about the game.
Since then a few more reviews have appeared, here's what they thought of Portal 2...
Specialist PC gaming site Rock, Paper, Shotgun described the sequel as "a refined, ludicrously detailed, and wonderfully smart game", while their is a brief "saggy moment toward the end".
Eurogamer echoed the positive sentiment and awarded Portal 2 a 10/10, saying "Portal is perfect. Portal 2 is not. It's something better than that. It's human: hot-blooded, silly, poignant, irreverent, base, ingenious and loving".
"Valve has created a masterpiece in Portal 2" says The Guardian, in its 5/5 review. "The depth of content, the mind-bending mechanics and fantastic experience are almost certain to satisfy ardent fans of the first game" but for newcomers "it's as simple as this: prepare to have your mind blown. Over and over again".
Adding to the numerous 10/10 scores is VideoGamer which says the first "ten minutes here will yield more memorable moments than you're likely to squeeze out of the entirety of most other games this year. In all aspects of its design, Portal 2 is genius."
Scrawlfx says "Portal 2 is one of the best puzzle games we've ever played" in its 9.5/10 review.
