Call of Duty: Black Ops 2 now 25 percent off on Amazon

Call of Duty: Black Ops 2 is on sale today for $45 on Xbox 360, PlayStation 3, Windows and Wii U through Amazon.

The sale is apparently a nod to Black Ops 2's latest downloadable content, Revolution, which released today. Revolution is priced at $14.99, the amount buyers will save if they take advantage of the sale.

Revolution includes four new multiplayer maps, a new zombie co-op map and a Peacemaker hybrid weapon. Check out the latest trailer and screenshots here.
