Exploring the Free Roam mode after finishing Firewatch on the Nintendo Switch unlocks the Free Roam mode. In the mode, it is possible to access a mini-game called Forrest 64 - a tribute to Nintendo 64 games such as Super Mario 64 and Banjo Kazooie where the player plays as Forrest Byrne.
Forrest 64 is divided into three sections
- a collectathon
- a mode where you destroy red rocks
- a foot race with a UFO
It is unknown what beating the foot race achieves, because the video of Super Nintendad playing it ends with him losing, and the person writing this segment couldn't be bothered to beat the the mini-game himself.
