As part of its ongoing Ultimate Game Sale, which is taking place all this week, Microsoft has announced the latest franchise to put most of its installments at a bargain price – and it's none other than Assassin's Creed.

Although Assassin's Creed III's markdowns are nowhere to be found (c'mon, it's on PlayStation Network for $35!), other games are available for cheap.  The original Assassin's Creed, Assassin's Creed II and Assassin's Creed Brotherhood can be yours digitally for $9.99 a pop, while Assassin's Creed Revelations, the sweet cross-over chapter of the series, is all yours for $14.99.  The sale continues through today only, so if you love sneaking up on targets and running along rooftops, you won't find a better opportunity to get some deals.

For that matter, we'd also like to remind you that the Ultimate Game Sale includes some awesome deals on other games, running now through March 5th.  DiRT 2 and GRiD, two of Codemasters' better racing games, are five bucks a pop; and the underrated action game El Shaddai is a mere $2.99.  Stock up your cash and get to spendin'!
