On April 1, 2022, Adam “adamgryu” Robinson-Yu released the A Short Hike 99 online multiplayer mod.
Here’s the official A Short Hike multiplayer mod announcement, which also includes a gif of three people playing on the volleyball court.
The announcement warned that it is “rough” and won’t be added as a full, official mode. Adamgryu’s A Short Hike multiplayer server will only be up for a brief time.
A Short Hike is available on the Nintendo Switch, PS4, Xbox One, and PC.
