The third piece of downloadable content for the recent Call of Duty: Black Ops first-person shooter may have been leaked onto the web, as a new blurry photo of a flyer presents the five new maps that will be added to the game.

Call of Duty: Black Ops is currently one of the best-selling games of all time and one of the most popular entertainment releases in the last couple of years, beating movies and books.

As you can imagine, any details about downloadable content for it are extremely important, and we've already seen the second map pack, Escalation, be leaked days before its official announcement.

Now, it seems that third DLC for Call of Duty: Black Ops receives a similar treatment, with website Digital Warfare 24/7 posting a blurry photo of what looks like a flyer with details about the new map pack.

While the source isn't known, the flyer does seem to have originated from a GameStop store, due to the "Downloadable Content is better at GameStop" mention on top.

The flyer retains the same basic layout seen with the Escalation DLC that was leaked by another retailer earlier this year, highlighting the four new competitive multiplayer maps, alongside the new cooperative Zombies scenario.

The new maps are called Hangar 18, Hazard, Silo, Drive-In, while the zombies one is called simply Zombies.

The left part of the flyer is cut off, as it no doubt contained the actual name of the DLC as well as its release date for the Xbox 360, platform that traditionally receives Call of Duty map packs earlier than the PC or PlayStation 3.

According to recent rumors, the new Black Ops DLC could be called Retaliation, but it's unclear whether this will be the final name.

Expect more details about the new Call of Duty: Black ops DLC in the following days, as Activision is certain to make an official announcement in regards to the third and possibly last map pack for the game.
