EM1

The EM1 (ElectroMagnetic-1) s a heavy directed-energy weapon in Call of Duty: Advanced Warfare.

Twisted Dimension 63 Saga
The EM1 appears in Twisted Dimension 63 Saga zombies mode. It is available via 3D Printer in Forty-Five and Mystery Box in Sǐwáng Shèng Qì. Unlike its campaign and Multiplayer counterpart, the EM1 does not have unlimited ammo. The ammo is gauged by percentage, similar to a Ripped Energy Turret. However, this means that the EM1 will never overheat.

When Packed-a-Punched via Pack a Punch Machine, it will become EM115 Shaolin, attached with parabolic microphone and comes with 200%.
