Call of Duty: Black Ops 4 multiplayer beta
Last week, Treyarch revealed the dates for the Call of Duty: Black Ops 4 multiplayer betas, whichinclude both the early access betas and open betas.

PlayStation 4 players will be able to get an early jump on the action with an exclusive beta that runs from August 3 through August 6. An open beta for the PlayStation 4 and Xbox One runs from August 10 through August 13. The PC will have an early access beta starting on August 10 with an open beta beginning August 11.

The multiplayer beta will feature game modes such as:

In addition, the Pick 10 system returns which will allow you to create your own custom classes on a point based system. There are also new Special Issue Equipment given to each Specialist. These items do not count against the Pick 10 system. A new slot, Gear, looks to add an extra perk to your class such as faster healing, cheaper killstreaks, etc.

Weapons now have "unique sets of attachments." Some of these attachments are powerful and are being called "Operator Mods."

The PC beta will be exclusive to Battle.net, as will the full release of the game. This shouldn't come as any surprise at this point. The PC beta is being worked on by Treyarch, Blizzard, and Beenox.

And what about the promised battle royale mode for Black Ops 4? Well, Blackout as it's called, will have a private beta come September. Details on how you will be able to participate in this beta have not yet been revealed. I'm assuming pre-ordering will play a role. All we know for sure is that the Blackout beta will again appear first on the PlayStation 4.
