With less than a week before the beta for “Call of Duty: Black Ops 3” hits exclusively for the PS4 first, developer Treyarch has revealed a handful of details, including multiplayer maps, modes and some specialists that are default in the game.

Three multiplayer maps have been unveiled, all of which will be accessible in the beta. According to Treyarch’s recent post over its official community forums, the maps have been built from the ground up to tailor them to the chained-movement system.

Hunted is the first map, which is located underneath a waterfall and in the mountains of Ethiopia. The Combine map is set in the Sahara, where the fighting will take place in tight quarters and a flank path. The last map will take players to Singapore’s quarantined zone.

There are a seven game modes coming to the beta of “Call of Duty: Black Ops 3.” These include a number of fan favorites, including Capture the Flag, Demolition, Domination, Hardpoint, Kill Confirmed, Search & Destroy and Team Deathmatch.

Finally, there are eight specialists, each of whom will have their own personalities, abilities and set of weapons. Some interesting abilities of the specialists include Overdrive, which is a burst of speed in movement for a limited time, the Vision Pulse, which allows the player to reveal the location of enemies nearby, and Glitch, where the player can go back to his previous position using the system mod.

There are a few more specialists, some of which deliver a range of powers, including the ability to become invisible, simulate decoy clones and even recover from near death using a nanoparticle serum. Treyarch has also brought in a new feature, which is the Weapon Paintshop. With this, players can now customize the three sides of their weapons using up to 64 layers.

“Since this is a beta — and because it’s important that we stress test the game in particular ways —we will have gated progression caps along the way,” said Treyarch over its official forum.

Sadly, any unlocked weapon, specialist, gear or item during the beta will not be transferred to the base game once it releases, Charlie Intel reported. One reason for this is that the beta is supposed to test the game, instead of letting players access and advance in the game early.

In the meantime, Treyarch has already released a new trailer for the multiplayer beta of “Call of Duty: Black Ops 3,” seen below. The beta for the PS4 players will launch on Aug. 19. Xbox One and PC players will have to wait only a week to get their hands on the beta, which will launch on Aug. 26. All COD fans need to do is to preorder “Call of Duty: Black Ops 3” to access the beta.
