Backrooms Lost Runners

Halloween Update 2026

ShimStudioGames

Happy Halloween, Runners!

Something strange is happening in the Backrooms… and this time, it's Halloween!

To celebrate the spooky season, we've given several locations a Halloween makeover! Familiar environments now feature festive decorations, eerie details, and a completely different atmosphere.

But the locations aren't the only things that have changed. Some of the entities have also received a special Halloween-themed appearance!

Gather your friends, explore the transformed Backrooms, and discover what's changed. Even familiar places might surprise you!

Happy Halloween, and good luck out there!
