Description

The Backrooms Civilization is a survival horror game where you explore endless levels, gather resources, build bases, and fight to survive. Team up with others to form civilizations, or go solo and face the dangers alone. Every level has new threats, secrets, and challenges.

Membership history

Growth

2 measurements spanning 17 days, net +1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 11–12 and does not start at zero.
