Haven Below

The surface is ash. You lead the last Wardens into Haven Below — a sealed underground vault with a flickering Life Core, an empty build grid, and ten days until extraction.

Build the bunker. Drop Generators, Hydro Farms, Water Condensers, Dorms, Med Stations, Auto Turrets, Barricades and Scrap Vaults onto the vault grid. Power everything, feed your survivors, and shape the maze the mutants have to chew through.

Hold the line. Every day ends with a raid: the klaxon sounds, the blast door sinks, and the horde pours in. Grab supply crates, patch damaged barricades, and let the turrets sing. Well-fed survivors arrive between raids and haul in extra scrap — empty stores drive them away.

Bring friends. Up to four Wardens share one bunker: one grid, one stockpile, one Core. Solo works exactly the same — the mutants don't care how many of you there are.

• Grid-based base building with a real power, food and water economy
• Escalating 10-day campaign with three mutant types, win and lose states
• Repairable structures, supply-drop chases, turret defense
• Dark industrial vault atmosphere: amber work lights, glowing green reactor, drifting dust
