"The Ohm Weapon Pack features the Ohm directed energy two-in-one LMG/Shotgun and its Werewolf Custom Variant. Adjust the weapon on the fly to fit your strategy. Unleash a barrage of directed energy fire from a distance in LMG mode or get up close and personal in shotgun mode and deliver a concentrated blast. PLEASE NOTE: If you previously purchased Call of Duty: Advanced Warfare Season Pass or Ascendance DLC, do not also purchase the Ohm Weapon Pack, as you already have access to this content."
The Ohm and the Werewolf variant are available on Xbox 360 and One for $3.99. It should be coming to PlayStation and PC soon.
