The open beta will now conclude on Tuesday, October 20 at 10amPST/1pmET/6pm UK time.
At the current stage of the beta, Treyarch and Raven Software have updated all weapons to max level so fans will have the opportunity to use all attachments on some of their favourite guns.
The level cap is set at level 40 allowing players to unlock the majority of items that are available in Cold War.
This will be the final chance for players to play the upcoming shooter before it releases on November 13.
