To make sure you make full use every single minute of the beta for Call Of Duty: Modern Warfare, the developer will allow their PS4 players to pre-load the game first and they can start doing that now.
Of course, you have to be eligible for the beta testing first. The beta testing will go on from the 14th of September until the 16th of September but those that pre-ordered the game will get to play it on the 12th of September and the 13th of September.
For now, it will only be for the PS4 players while Xbox One and PC players will have to wait until the 19th of September to get their chance of testing out the game.
Call of Duty: Modern Warfare will officially arrive on the 25th of October which is a little more than a month away so even if you did not get to test out the beta, the wait will be over pretty soon.
