UPDATE: The giveaway is now closed; all winners have received their beta keys. Thanks for playing; now go wreck some fools!

In the Multiplayer Beta, players will begin fighting through six maps, two of which will make their first public appearance. Additionally, fans will play new Specialists and reacquaint themselves with returning Specialists--Nomad and Prophet--who will be bringing with them brand-new gameplay mechanics built for Black Ops 4. Additional info on the multiplayer beta can be found at Treyarch's community page.

A reminder that the multiplayer beta starts today Friday, August 3rd and is for PS4 players only.

Here's a handy guide to the Private PS4 Beta dates:

And here's when PC players will get to access the open Beta:

Modes of Play:

• The Private Multiplayer Beta will feature fan-favorite game modes like Team Deathmatch, Domination, Hardpoint, and Search & Destroy, alongside our brand-new objective-based game mode, Control, which was designed to bring out the best of Black Ops 4 Multiplayer gameplay.

• In Control, teams alternate rounds between attacking and defending two static objectives. Each team has a limited number of lives in this first-to-three wins match-up, so strategic strikes and defensive positioning are key, making for some fast and frenetic gunfights.

Gearing Up:

• We’ve brought the Pick 10 system back to Create-a-Class to give players complete customization over their loadout, and with its return comes a few new changes.

• Load out with Special Issue Equipment that’s designed exclusively for each Specialist without costing a point against Pick 10.

• Gear is an all new slot designed to up the ante on your style of gameplay. Need cheaper Scorestreaks? COMSEC Device. Heal faster? Stim Shot. Gain an advantage in situational awareness? Acoustic Sensor. Only one piece of Gear can be used per loadout, so choose wisely.

• Weapons now have unique sets of attachments, including a new class of powerful attachments called Operator Mods, to really focus each gun on its individual role in combat.
