A recent update for Call of Duty: Ghosts on PC accidentally opened up the developer playlists to the general public for a short while, allowing a little bit of information about forthcoming maps and updates to leak out in the process.
As reported by CoD fansite Charlie Intel, the playlists allowed players to get a look at some map names that will more than likely be appearing in as-yet-unannounced (but inevitable) DLC. Said map names included: Swamp, Battery, Rumble, Dome, Boneyard, Gaza, Comp and Red River. Those names may not be final, but Dome at least has been a map in a previous edition of the series.
To what should be the surprise of no-one, it also seems as if Extinction mode is getting some new maps too. These are still called “Level 2” and “Level 3” internally at the moment, as you can see from the screenshot below. Further dev playlist screens can be seen here.
Reminder though, you probably shouldn’t buy Call of Duty: Ghosts on the PC because it’s a bit rubbish. Even if it does give you periodic glimpses at future DLC.
