Previously, access to those players was limited to a 7-day timed trial but they will now be able to play, even if they have used their allotted demo time.
Access will be open from March 28th and runs through to March 30th.
This new access period will give all players the chance to experience the culmination of the Map Madness campaign, which tasked players around the world with hitting a tank destruction quota. The last map, Prokhorovka, is expected to be released on Friday March 28th.
