The New Order: Operation Deep Freeze

Operation Deep Freeze brings the seventh, frozen continent, Antarctica, to the world of TNO. The continent has been claimed and divided up between the three superpowers, and provides yet another point of contention in TNO's Cold War.


This release features content for the German Antarctic territory of Neuschwabenland, up until the end of the German Civil War. It includes several in-depth mechanics and Custom GUIs for use during your campaign, as well as over 280 events written by our talent writing team. Also bundled with this release is the 104.5 McMurdo Station Music Mod, which includes two custom songs composed specifically for Operation Deep Freeze!
Lore and information on the other Antarctic territories is also spread throughout this release, as well as a few extra events for other nations around the world pertaining to Antarctic affairs.
