PvPvZ offers a completely unique experience in World War Z, challenging you to outlive fellow survivors and the undead across a variety of competitive modes designed for 4v4 combat.

The zombie swarm storms the arena throughout the match, forcing players to battle each other and the horde while the tide of the fight can turn in an instant. PvPvZ includes five maps and the following multiplayer modes:

Scavenge Raid: Players race to secure resources across the map to win
Vaccine Hunt: Players must pick up and hold an object to earn points for the team
Swarm Deathmatch: Two teams go head to head in a bitter fight to the end
Swarm Domination: Capture zones to earn points and win a team victory
King of the Hill: Capture a single hill, then control it to earn victory points
