Released 3 October 2026. Back to the changelog. UCP patch notes.
Changes
New: Four special zombies join as the rounds climb. Bloaters from round 8 burst into toxic gas. Screamers from round 12 send nearby zombies into a sprint frenzy. Armoured zombies from round 16 take half damage and ignore headshots until their armour breaks. Stalkers from round 22 are almost invisible.
New: Round modifiers: from round 10 a round can roll Frenzy, Ironclad, Bloodlust, Swarm, Fog, No regen, Thick skulls or Toxic. From round 15 there is always one, from round 25 two, and from round 40 three.
New: Bosses now call in a pack of zombies at half health and enrage into a sprint at a quarter.
