Valve has revealed the first ten games that will launch on Steam via Greenlight. The list includes the long-awaited re-envisioning of Valve's very own Half-Life, called Black Mesa, which will be released on September 14th for free.

The list also includes the intriguing first person horror title from Lunar Software, called Routine. The game tasks players with exploring an abandoned moon base in order to find out what has happened to the people stationed at the Lunar Research Station. The game sounds like a pretty intense and hardcore experience, with Lunar Software confirming that there will 'no HUD, no health bars or points system... you must run, hide and survive the best you can against what lurks in the base.' Dare I say, Amnesia: The Dark Descent, in space?

Another interesting fact about this game is that Lunar Software are looking to implement functionality for the Oculus Rift virtual reality headset at launch. The team explain via their Greenlight page that 'we really believe that this horror experience will really make the most out of the headset!' To learn more about Routine, visit the game's website, where you can view a teaser trailer.

The last game I'll mention is Dream, which the developer describes as 'a first person atmospheric exploration game'. Players control Howard Phillips, a graduate lacking direction who obsesses over his dreams. The game lets players explore these dreams, which are filled with puzzles and secrets about Howard's life.

Dream is another game that plans to be Oculus Rift enabled at launch, which is planned for the summer of next year. To learn more about Dream, visit the game's Greenlight page here.
