Two new Specialists were announced for Call of Duty Black Ops 3 yesterday during a press release from Treyarch on their upcoming Beta.

The new heroes are Erin Baker, the Battery, and the unknown Spectre. Both classes will serve fairly standard roles within multiplayer. The Battery is a grenade-launching tank, while the Spectre is a blade-slinging hunter.

The Battery will be able to briefly activate a shield that protects from all bullets fired at her, living up to her name as “the Battery,” while the Spectre can briefly turn invisible to hide his nefarious stealth-killing antics with his somewhat unique wrist-mounted blade launcher, the Ripper.

If you’re curious on the lore of both characters, Treyarch has provided a bio for both in their Beta rundown that was released yesterday.
