Last summer Bertie spoke to a young man named Richard Seabrook who sent his game to Valve head honcho Gabe Newell in a nifty briefcase. The fate of the briefcase remains unknown, but the game within - Prospekt, a sequel to the Gearbox-made Half-Life expansion Opposing Force - is now available for pre-order on Steam with an 11th February launch.
That's right, Valve has approved Seabrook's expansion to its canon to be sold for monetary value. In this case Ł7.50 / $9.99 / €9.99 (though pre-order are 10 per cent off).
Propsekt is set in the Nova Prospekt prison introduced in Half-Life 2. Series stalwart Gordon Freeman is cornered, so his Vortigaunt allies teleport in US Marine Adrian Shepherd - that's you! - to help out.
Seabrook has touted Prospekt as being comparable to Half-Life 2: Episode One in length, so somewhere between two and four hours depending on your playstyle. It will feature 13 levels, new music, voice acting, enemy AI, and a return to Xen, the alien planet introduced in Half-Life's final act.
Despite being set in the Half-Life universe, Prospekt won't require either parent game to operate as it's being sold as a standalone entity (and was made by a standalone entity, for that matter).
"I can't thank you all enough for voting this through on Greenlight and helping me get to this stage," Seabrook said in a Steam update. "Without you all I really wouldn't be writing this out today. Also, a massive thanks to Valve for their support."
