Playable so long as a user has a Source-powered game installed--such as Counter-Strike: Source, Half-Life 2 or The Orange Box--the mods will appear under the My Games listing, and will receive automatic updates like any other Steam release.
The initial batch of mods slated to arrive this week are:
- Age of Chivalry
- Zombie Panic
In addition to automatic updates, the mods will incorporate other aspects of Valve's Steamworks toolset, with the company promising that this will result in "stat tracking and tighter integration with the Steam community."
