PORTAL 2 (PG)
PC, PS3, Xbox 360, $89.95/$109.95
★★★★ The original Portal stood tall for two reasons: clever puzzlebased gameplay and great writing. In these departments the sequel doesn’t disappoint. Once again players are using a portal gun to bend the laws of space to connect disparate locations, but this time puzzles utilise more elements and are more varied. The single-player story’s not that difficult, but the co-op campaign, where two players have four portals with which to work, is a challenge.
