Classified is a reimagined version of "Five" from the very first Call of Duty: Black Ops and sees players who control Nikolai, Dempsey, Takeo and Richtofen. Although most similar to the original iteration, Classified includes new rooms like Server Room and Central Filing.
New Mystery Box sites, Perk-a-Colas removal and a new way to unlock the Pack-A-Punch machine have also been implemented. If you do not own Black Ops Pass, the base game still has three Zombies maps to enjoy Blood of the Dead (which features Primis), Voyage of Despair and IX. However, there are also Custom Mutations for changing game experiences and limited "Calling" events.
Call of Duty: Black Ops 4 is now available worldwide for Xbox One, PS4 and PC.
