Build a bunker to survive zombies tycoon

Build a Bunker to Survive Zombies Tycoon is a zombie-apocalypse tycoon on Roblox by Fractured Column, released in March 2023. Players hire researchers to study zombies, sell research at dedicated map locations for Cash, build and upgrade a survival bunker, and eliminate zombies for bonus income. With 87.8 million visits since launch, it has built a substantial audience over more than two years of operation.

The active delivery mechanic sets this game apart from purely passive tycoons. Researchers generate Research currency automatically - including while offline - but converting Research to Cash requires physically driving a vehicle to one of three sell points on the map. Players must manage researcher output alongside active delivery runs. Core systems include:

• 💼 Researchers - hired NPC workers that passively generate Research currency around the clock
• 🚗 Vehicle delivery - drive Research to one of three map sell points to convert it into Cash
• ⚔️ Zombie combat - eliminate zombie attackers for bonus Cash using weapons and special vehicles
• 🏠 Bunker upgrades - build and expand the tycoon base using collected Cash
• 💰 Offline income - researchers continue working while disconnected, accumulating Research for collection on return

Eight gamepasses are available, ranging from the 2x Cash multiplier and 2x Carry Capacity to the Autosell Mailbox (which automates Research delivery entirely) and combat weapons including a Minigun, Tank, and RPG. The Autosell Mailbox is the highest-value pass for players who prefer passive play, converting an active delivery loop into a fully idle experience.

Joining the Fractured Column Roblox group grants a free gun, adding an immediate combat advantage. For a survival-building game with a nuke-cycle mechanic instead, Build a Bunker! offers a more action-focused survival format.
