Microsoft is gearing up for 2015 by expanding its collection of countdown deals and is adding some Assassin's Creed games to the list.

If you want another look at the games that preceded Assassin's Creed Unity, you've found it with Microsoft's Coundown to 2015 Sale, Major Nelson's blog reports. The sale boasts new deals every day as well as weekly deals. For today's exclusive deals, you can get Assassin's Creed IV: Black Flag on Xbox One for 50 percent off and Assassin's Creed Liberation HD on Xbox 360 for 75 percent off.

You can either head on over to the Caribbean to be a pirate in Black Flag or traverse to Louisiana to battle throughout the French and Indian war in Liberation HD. Either way, you will be transported into the historical action-adventures that the Assassin's Creed series is known for.

Microsoft will be putting out new deals every day until Dec. 31 so make sure to check back to see what else it has up its sleeve. Just make sure you take advantage of this deal before it's gone.

Better dispose of the body before it's too late.
