Steam Adds Third-Party Game Mods, Red Orchestra Selling for $5

Not content with offering up user-created mods for Valve-developed Source-engine powered games, Valve has expanded Steam's offerings to include free mods for Tripwire's 2006 first-person shooter Red Orchestra: Ostfront 41-45 (PC).

Available now, the first Red Orchestra mod on Steam is Mare Nostrum, which brings three nationalities to the game along with 8 new maps, 8 weapons, and 10 vehicles.

In celebration, Tripwire has dropped the price of Red Orchestra to $4.99, a 75% price reduction that will run until the end of the weekend.

Upon purchasing Red Orchestra, any compatible mods will be listed under the "Not Installed" portion of Steam's "My Games" section. As with the previous batch of mods, the community-made Red Orchestra add-ons will be automatically updated by Steam, just like any other game on the digital distribution platform.
