Black Ops III Zombies as a Cyberpunk merc squad: cyberware powers, Cyberpunk guns and Pack-a-Punch upgrades.
How to join the host opens Zombies, starts a private match and invites friends from the lobby through Steam; friends accept the Steam invite to join the host's lobby, then the host starts the match. Public matchmaking isn't supported.
Play Call of Duty: Black Ops III Zombies as a Cyberpunk 2077 merc squad.
When you press Play, Cybermercs checks your own Cyberpunk 2077 install for the weapon and cyberware records it uses, then opens Black Ops III with the mod loaded. Nothing from either game is copied or included: you need both games installed.
What you get
Playing together: private co-op for up to 4 players. Everyone in the squad needs Cybermercs installed. Join through the game: the host opens Zombies, starts a private match and invites friends from the lobby through Steam; friends accept the Steam invite to join the host's lobby, then the host starts the match. Public matchmaking isn't supported.
If Black Ops III stays on a black screen at startup: turn off unused speakers and microphones in Windows Sound settings, especially virtual audio devices like Voicemeeter. Black Ops III can freeze while checking a long list of audio devices. This is a Black Ops III issue, not the mod.
