New Features

Quick Join

  • Finds an available match with a free slot and adds you either as the monster or prisoner player

New Structure - Barracks

  • New ‘stage one’ sector called the Barracks

  • Older part of the Sea Fort turning the area into a small military base including a war room, armoury, canteen and their living quarters

  • Designed as a group of smaller buildings with connecting alleyways and catwalks

Sea Fort Size Reduction

  • Reduced the size of the sea fort to now have only one starting sector instead of two

  • Reducing the map to a single Sector before the Power Plant phase has led to a much tighter map, for Prisoners the Monster is always close and the danger feels far greater

  • The single Sector still contains six Power Switches and two more have been added to the exterior areas along with one of the spawning rooms.

Monster Window Traversal

To increase the maneuverability of the Brute and the Malacosm in a chase, these monsters now have the ability to vault through windows.

  • Brute and Malacosm vault through windows by pressing the jump key whilst near a valid window

  • Brute completes a vault in 3 seconds

  • Malacosm completes a vault in 2 seconds

  • Prisoners cannot vault through the same window a Monster is currently vaulting




  • Added more Sledgehammers, Boltcutters, Welders and Tape to the item pools

Mission Time

  • Powerplant section of the game has now been given its own timer

  • Time to complete the Powerplant section will be dependant on the amount of Prisoners remaining as the last power switch was completed: 1 Prisoner - 10mins 2 Prisoners - 9 mins 3 Prisoners - 8mins 4 Prisoners - 8mins

General Movement

  • Reduced all character movement by 15 to 20% to take the smaller layout into account

  • Moving backwards has a lower maximum speed to prevent being able to man-oeuvre at maximum speed and get a free look around for the Monster or Prisoners.


  • Prisoner walk speed changed from 3.7m/s to 2.96m/s

  • Prisoner sprint speed changed from 5.18m/s to 4.14m/s

  • Prisoner crouch speed changed from 2.775m/s to 2.22m/s

  • Can no longer slide backwards or to the side

  • Sliding can only be done every 2 seconds

  • Monsters cannot attack whilst being slowed down

  • Monsters cannot attack Mid Air

  • Cooldown between attacks increased to 2 seconds

  • Range of attack decreased from 2m to 1.75m


  • Brute roar tracking is no longer a static sphere, but will now track the Prisoner’s movement for the duration of the ability

  • This effect will hide if a tracked Prisoner enters a hiding spot, and will reappear if they exit before the duration is completed

  • A prisoner who was hiding as the Brute started to roar will not be shown, even if they exit the hiding spot.

  • Brute roar range set to 40m

  • Brute walk speed changed from 3.6m/s to 3.04m/s

  • Brute sprint speed changed from 5.25m/s to 4.4m/s


  • Bhagra movement speed changed from 4.4m/s to 4.14m/s

  • Bhagra ceiling crawl speed changed from 7.6m/s to 6m/s


  • Malacosm cannot spam placement of teleporters - 8s cooldown

  • Malacosm walk speed changed from 3.25m/s to 2.7m/s

  • Malacosm sprint speed changed from 5.2m/s to 4.32m/s
