Blight: Survival Co-op Play for Up to Four Writhens

Blight: Survival supports seamless co-op for one to four players. That range covers quiet duos and full fireteams, all against AI humans and monsters—not against other players at launch. This guide focuses on communication, role variety, and extract discipline so co-op multiplies power instead of multiplying mistakes.

Agree on the mission contract

Before you drop, state the goal: tutorial learning, loot farming, or deep push. A squad that splits between “we extract at half bags” and “we go until wipe” will argue mid-fight. Write the contract in chat. Revisit it after each major objective using the framework in Mission Survival.

Diversity over quadruple mirrors

Because loadouts are weapon/armor/talent driven rather than rigid classes, you can still specialize. One player leans Zweihander posture breaks, another stays mobile with blades, a third prioritizes support talents when those toolkits expand. Skim Talents and Armor so nobody stacks the exact same weakness.

Callouts that matter

Prioritize: special enemy spawns, player downs, ammo or remedy locations, and extract readiness. Skip novel-length lore mid-combat. If voice chat fails, establish ping meanings before the run—especially “hold,” “pull back,” and “commit.”

Revive and risk economy

In extraction-lite structures, saving a downed teammate deep in a nest can cost the run. Decide thresholds: always revive in cleared rooms; only revive in hot zones if two players can cover. Solo players reading this should still understand co-op revive greed—see Solo for the opposite pressure profile.

Loot etiquette

Set need-before-greed rules for unique weapons and armor sets. Rotate pickups if the build is cosmetic-plus-stats. Nothing ends friendships faster than silent vacuum looting before a wipe.

Cross-play and platforms

Cross-play is planned for launch across PC and consoles. During playtests, confirm whether your wave is platform-locked. Keep Platforms & Release handy for the public platform matrix.

Training plan for new squads

Run a low-stakes playtest session focused only on posture coordination: one player intentionally draws attention while another practices flank finishers described in Posture & Finishers. Then attempt a real extract-focused mission. Review deaths without blame.

When co-op feels worse than solo

If your group tilts, shrink to two players or switch to a learning contract for a night. Co-op is optional power, not a requirement. The campaign is designed to stand alone—use that safety valve.

Four-player social roles without classes

Player one breaks posture with heavies. Player two flanks with blades. Player three stabilizes with guard tools. Player four manages bags and calls extract. Rotate the bag manager each mission so greed does not fossilize on one person.

Cross-play scheduling caution

Confirm whether your wave is cross-play enabled before promising a console friend a slot. Platform-siloed tests are common before launch tech matures. Keep Platforms & Release open while you schedule Blight: Survival sessions.

Co-op contracts that survive fog

Ping discipline, extract votes, and doorway order matter more than DPS fantasies. Keep a written contract beside Extraction Loop.

Cross-play parties

Launch cross-play is confirmed, but playtest platforms may differ (Cross-Play). Always verify the wave’s platform rules before inviting console friends.

Role diversity

Mix tempos: one heavy, one skirmisher, one stabilizer. Four Zweihanders is a meme, not a plan.

Closing note

Co-op excellence is boring on paper: pings, votes, doorways, and shared extract rules. That boredom is how Writhens come home with progress.

Invite hygiene

Only share playtest invites according to NDA and wave rules. Co-op excitement dies when a banned clip or leaked build burns trust with Behaviour’s Playtest Squad. Protect the pipeline so more friends get turns later.

Post-wipe co-op reset

After a wipe, take sixty seconds of silence, then each player names one fix. No speeches. Return to hub rules and relaunch. Short resets preserve goodwill across long Playtest Squad nights.
