Silverlode and FileFront are giving away 50,000 free copies of Saga on a first come, first served basis. The offer lasts until May 11, or as long as supplies last. The game is an effort at massively multiplayer real-time strategy in a persistent world, complete with solo quests, cooperative play, PvP, and an auction system. Saga normally sells for $19.95 and there is no subscription fee to play, but they do sell booster packs which are a quick way to get some of the better units.
