Steam has kicked off another one of its popular weekend sales today, with Bethesda's acclaimed post-apocalyptic title Fallout 3 getting a nice 50% discount. This means the game will be available for just $25 on Valve's digital distribution platform. Unfortunately, that does not include any of the $10 downloadable expansions, so those looking for the absolute best deal might want to hold on until October when the game and its five DLC packs will be sold together in a $50 Game of the Year bundle.
Additionally the company announced an update to its Steam client and, for fans of the old Street Fighter franchise, it is offering a 10% discount on pre-orders of Street Fighter IV PC which hits next Tuesday.
