Impulse, the digital distributor now owned by videogame retailer GameStop, has announced that select Valve titles will now be available for purchase on the service.


The games that are available include:

* Portal 2
* Left 4 Dead
* Left 4 Dead 2
* Half-Life Complete
* The Orange Box

Half-Life Complete includes: Half-Life, Half-Life: Opposing Force, Half-Life: Blue Shift, Half-Life: Source, Half-Life 2, Half-Life 2: Deathmatch, Half-Life 2: Episode One, Half-Life 2: Episode Two, and Team Fortress Classic.

The Orange Box includes: Half-Life 2, Half-Life 2: Episode 1, Half-Life 2: Episode Two, Team Fortress 2, and Portal.

Why would Valve release their titles on a Steam rival? Put simply, the games still require the installation of Steam to run, so while Valve is only getting a fraction of the sales, they still get new Steam users.
