Somebody is knocking on the bunker door. You have to decide whether to open it.

From The Bunker puts a free demo on Steam as the PvE Survival Crafting Fest opens

[August 31, 2026] – A viral outbreak has emptied a quiet southern town. The people who survived it are packed into an abandoned bunker in the forest, and every day brings a new decision about who eats, who works, and who goes outside. From The Bunker, a survivor-management game from four-person independent studio DEM Games, releases a free demo on Steam on August 31 at 10:00 a.m. PT, timed to the opening of Steam’s PvE Survival Crafting Fest. 

You play the group’s leader. Survivors arrive with their own strengths, weaknesses and needs, and their physical health, mental state and willingness to fight for the group all trace back to how you lead them. Neglect someone and they may walk out. Choose wrong and they may not survive at all. The bunker is the other half of the job: a forgotten shelter you turn into somewhere people can actually live, while the infected, hostile factions and desperate looters press in from outside.

Key features include:

• Lead a group of survivors — Assign jobs, monitor morale, and balance hunger, fear and exhaustion before they tear the group apart.
• Defend your last refuge — Build generators for electricity, upgrade boilers for clean water, raise barricades against infected hordes, and set traps for nighttime raids.
• Venture beyond the bunker — Search ruined streets, abandoned shops and military depots for weapons, food and medicine, and weigh the risk of every expedition against what the group needs.
• Every choice matters — Over 300 narrative events force hard calls that shape the group’s future, with different outcomes and endings depending on what you decide.

From The Bunker is a single-player game. The free demo goes live on Steam on August 31 at 10:00 a.m. PT as the Steam PvE Survival Crafting Fest begins. The full game is currently in development.
