Portal 2 has surged to the top of this week's UK Charts following unilateral critical acclaim from reviewers last week that included a perfect 10/10 score from TVG.
The game is one of three new releases this week, with Mortal Kombat landing at No.2 and Codemasters' Operation Flashpoint: Red River debuting at No.6.
Elsewhere, a price promotion on Call of Duty: Black Ops moved it from No.9 to No.3 and last week's No.1, Zumba Fitness, dropped down to No.4.
