Final Fortress: Idle Survival

Somehow you survived the outbreak. Now the world belongs to the idle undead, and the only currency that matters is gas. Build your fortress level by level—bedroom, garden, kitchen, clinic, workshop, communications, laboratory, sniper tower—recruiting survivors into specialist roles as your community grows. Gather stray clans, upgrade your vehicle to range further, and rebuild stronger each time you move on. The longer you survive, the more powerful your next fortress becomes, and there is no ceiling on how far you can push it.
