Please welcome, Portal 2

Legions of Portal fans may well get their appetite for more mind-bending puzzle action satiated, with the game's lead designer Kim Swift suggesting another slice is currently in the mix.

Valve's superlative first-person puzzler scooped the top prize at this year's Game Developer's Choice Awards and, in a post-acceptance interview, Swift spoke briefly about a follow-up, saying, "I believe [Valve Community Manager] Doug Lombardi has announced a sequel". Lombardi has indeed spoken about a second Portal game, saying last January that "There'll be more Portal, for sure. But the details of that, to be honest, we're still working out."

With a strong and highly vocal fan-base already present just months after the game's release, a sequel would surely incite the fervered drools of many a gamer - although, given Valve's usual protracted development periods, don't expect it for a while yet.
