It’s not Half-Life 3, but it’s certainly something. Prospekt is a new game built with Valve’s blessing by 25-year-old developer Richard Seabrook. What started as a simple demo for a job application to the popular gaming company has turned into a full-fledged game.

Rather than picking up where Half-Life 2: Epsidoe 2 left off, Prospekt is a continuation of the story introduced in Half-Life: Opposing Force.

In Prospekt, Gordon Freeman is cornered and being overrun by soldiers in the Nova Prospekt prison; the player controls US Marine Adrian Shepherd – the unsung hero – as he’s teleported in by Freeman’s Vortigaunt allies to help fight back.
