The Outlast Trials Chemical Leak Update

Red Barrels is back with another major update for The Outlast Trials, and this one brings the Chemical Leak limited-time event.

The game’s Season 7.1 patch will show up for console gamers as The Outlast Trials update 1.64/1.000.062, and this also adds new store items and a slew of gameplay improvements.

Check out the trailer and gameplay changes made in the complete patch notes.

The Outlast Trials Chemical Leak Update Adds New Events and More

This update includes

  • New Limited-Time Event: CHEMICAL LEAK
  • New Limited-Time Catalog: CHEMICAL LEAK
  • New MK-Challenge: CHANGE THE PROGRAM
  • New MK-Challenge: FUND THE CAMPAIGN
  • Various bug fixes and improvements.

New Limited-Time Event: CHEMICAL LEAK

Poison is an intoxicating embrace that suffocates the body, just as false idols poison the beliefs of the weak, uneducated, and vulnerable. Shut off the valves, breathe freely, and remember that therapy is the only answer.

Variators:

  • CHEMICAL LEAK -A chemical leak is filling the Trial with toxic gas. Find the valves to clear the gas from each area.
  • SHUT OFF THE VALVES – Shut off the valves in the Trial to stop the chemical leaks.

The event runs from Tuesday Sept. 8 (10AM ET) until Tuesday Oct. 6 (10AM ET).

New Limited-Time Catalog: CHEMICAL LEAK

  • A brand new Catalog is available for the duration of the Chemical Leak Limited-Time Event.
  • Players can spend their acquired Event Tokens in the Catalog to unlock exclusive rewards.
  • Once the Chemical Leak Event concludes, the Catalog will be removed and any unused Event Tokens will be forfeited. Be sure to spend your Event Tokens before the end of the event on Tuesday Oct. 6 (10AM ET).

New MK-Challenge: CHANGE THE PROGRAM

You are the hammer in the hands of a child, to shatter the fragile swine who would separate success from the government it created. Money is the future of speech. Fund the campaign and we will let you out.

Additions/Fixes/Balancing

Invasion

  • Evasive Manoeuvre: Now counters Backstabs by triggering a STRUGGLE instead, and win STRUGGLES more easily against Imposters.
  • Neuroshock: Now automatically pinged when thrown on the ground.
  • During the Exit Phase: When a Reagent is revived, an Imposter will spawn from a closet to match the new number of living Reagents.
  • Ex-Pops and Prime Assets will no longer target Reagents immediately after a Stab or Backstab.
  • Fixed an issue where the Steel Trap deployment audio could be heard from a very long distance.
  • Fixed an issue where players could body block other players (You can now push past a player of the opposing role who is blocking your path by walking into them for half a second.)

Escalation

  • Removed Broken Reagent from the variators pool.
  • Improved Escalation run stability to reduce server disconnections.
  • Players can now restore their save after a disconnection or crash.
  • Escalation Trial #21 and above: Damage is permanent throughout the run, and Revives are no longer available, making higher-level Trials even more challenging.

General

  • Improved online stability, including rubberbanding, lag, and disconnections. We will continue monitoring performance and making improvements as needed.
  • Player loadouts are now displayed in the Pause Menu.
  • Rebirth: Loadouts are no longer reset after completing a Rebirth.
  • Reworked Biter speed and aggressiveness, and slightly increased its chance of breaking the chain.
  • Slightly increased Kress Twins chase speed.
  • Slightly reduced Arora throw cooldown.
  • Fixed the price of the Jammer Rig skin in the Project Boneyard Catalog. It now costs 30 (was 75).
  • Fixed the rarity of the Project Boneyard poster. It is now Classified (was Basic).
  • Fixed the numbering of the Hopscotch floor game in the Orphanage, making it playable again.
  • Mods support is no longer available. While we recognize that mods can offer useful customization, some can provide gameplay advantages or alter the game in unintended ways. To maintain a fair and consistent experience for everyone across all game modes, mods are no longer supported.
    • We’ve added several new options to the Settings menu, including quality of life features that were previously available through mods. These are now built directly into the game and available to everyone:
      • Field of View — Slider
      • Camera Shake — Slider
      • Motion Blur — On / Off
      • Film Grain — On / Off
      • Chromatic Aberration — On / Off
      • Lens Flares — On / Off
      • Vignette — On / Off
      • Bloom — On / Off
      • Startup videos — On / Off
      • Toggle HUD Display — On / Off

Given how Red Barrels handles major updates, we fully expect a hotfix or two to be released in the same week. Once we receive one, we’ll let our readers know.
