Re: Minor containment event

Deep under the ground, Halden-Voss Life Sciences ran a few experiments with five anomalies. The experiments have now run into the staff.

Your remediation team is hired to go down, hold the line wave after wave, and clean up the specimens formerly known as colleagues – using the very substances that caused the mess.

Survival is encouraged but not compensated.

Field manual

One more wave. Always.

Short sessions, loud guns, and a build that gets out of hand in the best way. Great solo, better with friends.

01

Waves that escalate

Shamblers first, then runners, then sprinters. Every wave hits harder until only the best builds hold.

02

Co-op for up to four

Pick each other up, crawl and keep shooting when you are down, mark targets for the team. Late joiners jump in at the next wave.

03

A new sector every run

Rooms, wings, upper decks and loops are put together fresh each deployment – plus sector conditions like blackouts and floods.

04

Twelve weapons

From the service pistol to a grenade launcher called Hostile Takeover. Wall buys, the Requisition Terminal, and the Anomaly Reactor to infuse them.

05

A build every run

Pick a Management Directive after each wave, buy MedVend serums, and push your favourite gun up the Ascension tiers.

06

Punchy and messy

Hit-stop, screen shake, limbs that come off and specimens that crawl on. Every hit is supposed to feel good.

Hazard register

Five anomalies

Infuse your guns at the Anomaly Reactor. Two anomalies on one specimen react – and two players with two anomalies react harder.

Cryo

Slows with every hit, freezes solid at full chill. Chilled kills shatter.

Thermite

Sets specimens alight. Burning kills char to ash.

Volt

Builds a charge. Full, it discharges into everything nearby.

Mycel

Poisons. Poisoned kills burst into spores that infect the crowd.

Null

Marks targets for more damage and drags the crowd in around them.

Reactions include Thermoshock, Superconductor, Electrolysis, Deflagration and the Gravity Well. Halden-Voss accepts no liability for any of them.

Personnel files

Former colleagues

Most of the staff just shamble at you. Some of them kept their job description.

Security

Warden

Armoured, charges through the crowd and grabs contractors. His power pack is on his back.

knife him. three times.
Terminated
Animal care

Handler

The old animal keeper, now on all fours. Crouches, screams, then pounces on where you are about to be. Hunts in packs.

Facility maintenance

Vent Tech

Climbs to the ceiling, scuttles over your head and drops on you.

Head of logistics, welded into a cargo exosuit. Shoot the drill, the launcher and the legs off one by one.

Closed alpha

Your shift starts now

ZectorZero is in closed testing with friends and selected testers. Got an access code? Then the next deployment is waiting for you.
