Call of Duty: Black Ops 2 map Nuketown 2025 has been re-created in its entirety at the Paintball Explosion park in Illinois. The company has posted video footage of players running around the map and splattering each other silly.
The map is called 'Nuketown 2013', and development was sponsored by paintball firm Tipmann Sports. You can check out a gallery of images from the map over at their Facebook page.
I went to CoD XP back in 2011 and played paintball on their re-creation of MW2's Scrapyard map. it was quite surreal, and we got battered by a squad of - honest-to-god - US marines. My pride and wounds have never recovered.
