New details regarding the upcoming Call of Duty: Black Ops map pack have been revealed, via GAME Australia's website. It's difficult to garner too much info, but the pack in question is called 'Escalation' and looks to feature a new Zombies map, in addition to the new multiplayer arenas.
Once again, it's tough to gather any real concrete info from this reveal, but a map... in a zoo? That's bound to be... interesting. From the wording it also looks as though each map has been designed around specific objective based game types.
The date on the advertisement is May 3, but we're unsure whether that's just the date the expansion will go on sale at retail, or whether that's the date it'll go onsale digitally as well.
