This new mode has been a "popular request" by players, but Update 8.11 also adds a new winter battle arena called Windstorm and a wintery Himmelsdorf, with Ruinberg also revamped.
Expect rainfall and fires now in Ruinberg, along with a new snowy coat for Himmelsdorf. The new Windstorm is a European set battle arena, reveal Wargaming.
"We have always valued World of Tanks community's feedback above all else," said World of Tanks Lead Producer Mike Zhivets. "The combat mode with national teams has been a popular request from our players for quite some time, and we are excited that they will soon be able to try it out."
