With Call of Duty: Modern Warfare a few months away, Treyarch is still hard at work updating Call of Duty: Black Ops 4.

A new [i]Black Ops 4/i] update, titled "Operation Apocalypse Z" has dropped on PlayStation 4 with other platforms coming soon.

Operation Apocalypse Z brings a host of new undead features to the multiplayer shooter including the return of Reaper who made his debut in Black Ops 3. Reaper wields a Scythe heavy machine gun and the Radar Shroud; "a versatile deployable jammer that blocks enemies from using minimap information within its radius."

Black Ops Pass owners will also gain access to three new maps to wage war on, including two new Zombies-themed battlegrounds.

A welcome return in the new update is the first-time inclusion of the "Sticks and Stones" mode in [i]Black Ops 4[i], which sees players battling it out in a frenzied free-for-all using only Ballistic Knives, Combat Axes, and the new Auto-Crossbow.

Zombies mode is also getting some love with “Alpha Omega” which will see players take on the role of "both the Ultimis and Primis crews for the first time in Zombies history." Alpha Omega is a sizable update with "400% more area to explore than the original Nuketown Zombies and over twice as much written dialogue compared to previous Zombies experiences."

There's a whole bunch more content in the new update, which you can read about right here.
