Wargaming.net has announced that World Of  Tanks will get an open beta on PS4 from December 4th until December 6th. The developer confirmed that the PS4 version will be separate to the other versions, which means that progression that has been made elsewhere will not carry over. The beta won’t require any signing up so you’ll be able to enter the battle straight away.
At launch the PS4 version of World Of Tanks will contain the largest map made for the game, which will be exclusive. The studio also confirmed that any progress made in the beta will carry over to the full release of World Of Tanks. Each month after launch will see additional maps and tanks come online too.
