removedCreature AINo more wallhack retargeting • Creatures no longer switch targets to teammates they cannot actually see or hear. They have to detect you for real, which removes a lot of unfair ambushes through walls.
changedCreature AIRetreat behaviour feels less deaf • Creatures that are walking away can be interrupted by close-range player noise or sight. After a failed attack or after a player hides, they alert for a short window before disengaging instead of freezing in place.
removedLevel 0 (the Lobby)No more falling out of the map • The wall-destruction pass was being too aggressive and could remove a structural wall next to a destroyed placeholder. Each pass now removes exactly one wall, the right one.
fixedLevel 0 (the Lobby)Exit door always at the right position • Fixed a regression where the exit door (and the quantum room portal inside it) could spawn at the world origin, leaving a hole in the wall opening to nothing.
fixedLevel 26 (Fun)Partygoers use the plastic tubes again • The crawl tunnels were essentially being ignored by the AI, forcing creatures into long detours. Many of you reported partygoers stuck at the entrance or refusing to follow through • that is fixed.
removedLevel 26 (Fun)Doors no longer block AI permanently • When a door opens, the navigation around it now updates correctly so creatures can actually walk through. A handful of "creature blocked at a doorway" reports came from this.

Creature AI

  • Camping enforcement • Creatures that spend a long time around a hiding spot now retreat far away instead of lingering. So many of you reported being trapped in a cabinet or closet while a creature just refused to leave • this is the biggest fix in this update.

  • No more wallhack retargeting • Creatures no longer switch targets to teammates they cannot actually see or hear. They have to detect you for real, which removes a lot of unfair ambushes through walls.

  • Retreat behaviour feels less deaf • Creatures that are walking away can be interrupted by close-range player noise or sight. After a failed attack or after a player hides, they alert for a short window before disengaging instead of freezing in place.

  • The Wretch and the Hound • Both stop camping around downed or hidden players, and properly leave the area when they lose track.

  • The Smiler attack now reliably knees you • Several of you reported the Smiler reaching you, fully playing its attack, but the player never going down. The kneel is now guaranteed at the moment of the attack.

Level 0 (the Lobby)

  • Exit door reachable for clients • The big one. Multiple reports of being unable to walk through the exit because invisible walls were still there client-side. The destruction of those walls is now replicated to every player, so the host and clients see the same opening.

  • Hiding spots cleared on every client • Cubbies in the lobby are now unblocked for everyone, not just the host. No more "this hiding spot is blocked by a wall I can't see."

  • No more falling out of the map • The wall-destruction pass was being too aggressive and could remove a structural wall next to a destroyed placeholder. Each pass now removes exactly one wall, the right one.

  • Exit door always at the right position • Fixed a regression where the exit door (and the quantum room portal inside it) could spawn at the world origin, leaving a hole in the wall opening to nothing.

Level 26 (Fun)

  • Partygoers use the plastic tubes again • The crawl tunnels were essentially being ignored by the AI, forcing creatures into long detours. Many of you reported partygoers stuck at the entrance or refusing to follow through • that is fixed.

  • Doors no longer block AI permanently • When a door opens, the navigation around it now updates correctly so creatures can actually walk through. A handful of "creature blocked at a doorway" reports came from this.

  • Partygoers can ambush from the pipes • A data error meant partygoers were silently rejected from pipe spawn points, so they never dropped from the pipes in Fun. Now they do.

Multiplayer & Co-op

  • Co-op pressure spreads out • When a partygoer ambush triggers, the target player rotates fairly across the team. Previously the player nearest to the spawn point caught everything; now creatures pick the least-targeted player on the team.

  • Hand-placed walls clear for everyone • Walls placed by hand in the level (not just spawned at runtime) now also disappear consistently on every client.

Balance & Tools

  • Smiler appears closer • The Smiler now spawns at a tighter range during the blackout, which gives you less time to react but makes the encounter feel intentional rather than telegraphed from across the room.

  • Fog horn pops balloons in front of you • The fog horn now actually pops balloons in a forward cone, and grants a small mental relief when it does. Useful when you're being mobbed.

  • Balloon contact pop costs mental • A balloon popping right next to you now bursts a small chunk of stress (scaled by distance and difficulty), so the trade-off between popping and dodging actually matters.

Shipping Persistence

  • Custom level config sticks in Shipping • A memory-cleanup issue could cause Shipping builds to silently revert custom mission/level overrides back to baseline. Anyone hand-tuning a level for testing was hitting this.

Thanks again!
