The Assassin's Creed series is next up for some savin' in Xbox Live's week-long Ultimate Game Sale. Leaping into the half-price haystack for today only are the first four Creeds on Xbox 360, with Revelations at $14.99, and the others - AC1, AC2, and Brotherhood - $9.99.

A plethora of Games on Demand content is staying discounted until March 4, with some serious bargains up for acquirement. El Shaddai, for example, which JC gave four and a half stars to back in 2011, can be yours for just $2.99, a measly amount for a game that's "heavenly in both inspiration and execution."
