Update

: Looks like this was yet another false Half-Life-related alarm. Valve told IGN that it will show no games at Gamescom 2012.

Half-Life 3 may be officially confirmed and shown off for the first time at Gamescom 2012.The title appears on an official listing on the Gamescom site that proclaims all the games we'll be finding out during the show. However, according to the document's header, the Gamescom site basically says the information it lists is "Offered without proof/guarantee."The list also features BioShock Infinite, which Irrational said earlier this year would not be shown at Gamescom.Though never officially confirmed, followers of the series have been hoping for the title for an extended period of time. Frustration at Valve's refusal to discuss the sequel last year led to a fan driven campaign to force the company to talk, with limited success.There has been no word at all from Valve over whether this rumour is correct, and it seems unlikely we'll hear anything now until the reveal actually does (or doesn't) happen.We speculated earlier this year that the time was ripe for the company to reveal Half-Life 3 and, after a quiet E3 for Valve , it'll be interesting to see whether it's decided at long last to put us out of our misery.

Luke Karmali is IGN's UK Editorial Assistant and is bummed out that Final Fantasy Versus XIII didn't make the list. You too can revel in mediocrity by following him on IGN and on Twitter
