Apparently besides some fixes, nerfs, buffs and features in the next patch for Black Op’s 2, it will include Dinosaurs.
Treyarch’s David Vonderhaar has recently posted a small update on his Twitter account stating that “Still at work doing that final grind on the next update. It’s a big one. Nerfs. Buffs. Bug fixes. Features. Dinosaurs. Details to come.”
So could this be some type of new Survival mode? Who knows, but at least we’re going to get a gametype that features Dinosaurs, before DICE managed to include them in Battlefield 3.
