What is Sons of the Forest, the cannibal survival game that sold 2m copies in a day?

Endnight Games' sequel sold vast numbers on Steam. What's behind its remarkable success - and what should you know before you play it?

Late last month, a game called Sons of the Forest launched on the Steam Early Access programme, which allows players to buy unfinished games still in active development, and immediately became one of the biggest new titles of 2023. Within 24 hours, it had sold 2m copies, and it has remained near the top of Steam's top-sellers list ever since.

Sons of the Forest's phenomenal success has seemingly appeared out of nowhere, but the momentum has been quietly building for years. Canadian developer Endnight Games has carved out a niche, delivering immersive, tangible and thrilling survival games.
