We may not know just how many maps are going to be included with the Call of Duty: Ghosts season pass, but we might now know the names of all the map packs.
The names for all of Call of Duty: Ghosts' multiplayer add-ons were supposedly unveiled by Activision in an email to fans. According to MP1ST, the email was sent as a way to promote the season pass for Ghosts, and listed some brief details about the value and additional content included when purchased.
However, the email also included what appeared to be the names of the four packs, all of which are based on the name ODIN. Sound familiar? It's the satellite blown up in the early moments of the campaign. Onslaught, Devastation, Invasion and Nemesis were listed initially, but subsequent emails from Activision pulled the names from the images, and merely offered slight details on the pricing for the season pass.
The only real indicator we have that these names might be tied to the map packs is the quickness with which Activision acted in removing the proof after the email was sent. Since Ghosts only just launched earlier this month, it'll be a little while until the first map pack is released. Typically we'll see one about every three months until next year if previous timing is being followed again.
