Welcome to Duo Trials by Project Zaero.

  • This rundown is designed for duo play, starting with beginner difficulty leading into extreme intensity expeditions. Please report any issues you find to Project Zaero#9999 on Discord.


  • Verified duo clearable expeditions.
  • Progressively more challenging expeditions. A tier starts off beginner friendly, while E tier will challenge even the top 0.1% of duos.
  • 9 Expeditions currently available.
  • Main objectives are relatively easy, while sectors provide a significant challenge on all levels.
  • The first expedition of each tier will contain only vanilla enemies.

Vanilla enemy rebalances & reworks.

Striker: Unchanged.
Shooter: Damage increased 5% -> 8%. Adjusted homing properties, longer cooldown between shots.
Hybrid: Damage increased 4% -> 6%. Barrage pattern reworked.
Giant Striker: Adjusted stagger & limb health breakpoints.
Giant Shooter: Removed.
Charger: Tentacle nerfed 18% -> 16%, punch buffed 4% -> 6%. Much more stagger resistant.
Giant Charger: Animation speed upscaled proportionate to their size, so they no longer animate in slow motion. Greatly increased stagger resistance and limb health.
Tank: Adjusted weakspot health values. Increased aggression.
Birthers: Adjusted weakspot health values. Significantly reduced animation speed.
Child Striker: Dies instantly to any damage. Moves much slower.
Spitters: Damage 4% -> 5%.
Shadow: No longer react to movement unless you are very close, but instead wake up to flashlights. Significantly faster with reduced health.
Giant Shadow: Same detection behavior as small shadows. Retro/R2 style aggression but worse.
Shadow Scout: Adjusted detection cycle. Model fixed to be a shooter model.

Other notable changes.

  • Infection health decay rate increased by 25%.
  • "Armor" (white hitmarkers) on boss enemies now deals 35% damage instead of 0.0001% damage. If they're low, shoot them anywhere!
  • Pouncers no longer have armor.
  • Chargers have a critical point at the center of their chest, and take critical damage to their back, with an "occiput" style center of back super damage bonus.
  • Foam on the floor is massively improved for stalling enemies.
  • Custom syringes with special properties spawn on most levels. Try them out!
  • Bio-Tracker has color coded enemy tags, with varying icons to make special enemy variants stick out.
  • Resources and consumables can be dropped back into containers to assist in planning out encounters.
  • Health Regen Cap 20% -> 25%, medipack healing 20% -> 25%.
  • Some levels have enemies that inflict status effects, including Bleed and Infection. If you have the "Bleeding!" status effect, medkits and regeneration effects from syringes will stop the bleeding instantly.
  • If you see a shooter fire blue projectiles, you're already dead.
