First glimpse at 80's Verdansk from r/CODWarzone
The 10-second video showed a stadium, snow-covered expanses, a giant bridge, and so on. Also at the very end they showed the street of Verdansk itself. Judging by the weapons and environment, the events take place in the 80s of the last century.
This is also indicated by the absence of a dam, aqueducts and a radar station.
