Earlier today, Treyarch and Activision removed Nuketown 2025 from the online playlists. I know, interesting decision. Design Director David Vonderhaar said via Twitter that the map would be back for "special events."
"Double XP weekend is official [sic] over. That means Nuketown 2025 / 24-7 is as well. I know. RIGHT? Don't kill the messenger," he said. "Nuketown 2025 / 24-7 will be back for special events. You can always play it with your friends in Custom Games."
That's easily one of the dumbest things I've seen all year and both the developer and publisher realized that shortly after and brought the map back to a new playlist called "Chaos Mosphit"--where the Black Ops favorite is thrown in the mix with Slums and Standoff.
The map was initially just a pre-order bonus and has sense made it's way into normal gameplay and will remain that way (as it should have been from the start).
