After the announcement of Call of Duty: Black Ops on the Xbox 360 becoming backwards compatible on the Xbox One, sales of the game rose astronomically. On Amazon, sales rose by 13,400 percent while the Classics version sales increased by 5,971% percent.

The game is currently second on the retailer’s PC & Video Games sales chart (which changes by the hour), putting it ahead of DOOM and just under Uncharted 4: A Thief’s End. That’s a pretty strong jump especially since it was previously ranked in the 100s with regards to sales.

Despite the popularity of Black Ops 3, many fans have fond memories of the multiplayer in Call of Duty: Black Ops. Of course, it was also the first title in the series to introduce Zombies as a separate mode and helped cement it as a major staple in the franchise moving forward.
