Wrapping up the week of one-day sales on Ubisoft-published titles, digital distribution platform Steam is now selling a $10 bundle of four classic Ubisoft PC games: Beyond Good and Evil, Far Cry, Dark Messiah of Might and Magic, and IL-2 Sturmovik: 1946.

The sale, which runs all weekend, pretty much punches rival Good Old Games in the face. Just yesterday, GOG began selling Ubisoft PC games, debuting Beyond Good and Evil and IL-2 Sturmovik: 1946 at $10 each, with Far Cry and other games due soon.

In addition, Steam's $15 sale on Far Cry 2 has been extended to run all weekend.

French publisher Ubisoft has revealed that it is latest publisher to make its PC titles available via Valve's digital distribution platform Steam, with the upcoming PC release of Assassin's Creed: Director's Cut Edition currently available for pre-purchase.

The stealth title Tom Clancy's Splinter Cell and Crytek's non-linear shooter Far Cry mark Ubisoft's initial offerings, with Far Cry priced at $9.95 and Splinter Cell going for $19.95. Both will sell at a 10% discount until April 8.

Over 40 titles will be eventually be available, including Tom Clancy games, the Heroes of Might & Magic series, the IL-2 Sturmovik collection and more, along with upcoming releases such as Far Cry 2. According to Valve, bundles packaging franchise entries together will be available in the coming weeks.

"Ubisoft will be delivering the largest library of titles available from any single publisher or developer to Steam," said Valve business development director Jason Holtman, director of business development at Valve.

"We look forward to working with Steam and continuing to strengthen our commitment to the PC gaming community with innovative products and wider distribution channels, added Ubisoft senior sales director Andy Swanson.

3D Gamers is hosting an updated demo of IL-2 Sturmovik. A game which many say is one of the best flight sims ever. You can also grab it from the Ubi Soft FTP. The 146.5mb demo offers three new flyable planes (for a total of six), more AI planes and ground units, a 200x300km area single player map and various other things.
