So I don't see this very often, in fact I think that I have only seen it happen once before.. But this weekend has 2 games on free weekend status until Sunday at 1pm (PST?). COD: Black Ops 2 (Which also has double XP with the free weekend) and Gratuitous Space Battles. And as usual with free weekends, their respective games/dlc are on sell until Monday at 10am (also PST?).
