About This Game

VampOS is an incremental management game played entirely through a vampire’s operating system.

Eternity is a valuable resource. Why spend yours chasing dinner?

With VampOS, you can build a thriving blood business from the comfort of your desktop. Install applications, automate your operations, and turn mortal resources into immortal ambition. Keep the blood flowing, keep the humans unsuspecting, and prepare an offering worthy of the Blood God.

Every successful enterprise starts with a reliable supply.

RedHarvest.exe puts blood collection at your fingertips, while DonorNet.exe helps you cultivate a more sustainable relationship with your donors. Expand your human populations, acquire better equipment, and grow your operation.

A returning donor is a repeat customer. Depending on your business model.

You didn’t become immortal to do everything yourself.

Use Household.exe to turn humans into obedient Thralls and assign crews to repeatable work. Recruit Familiar supervisors, configure their policies, and upgrade your operations for greater speed and yield.

Just maintain their Mana supply. Even absolute loyalty has operating costs.

Raw blood is only the beginning.

Develop your own blood products in Hemotech.exe. Choose formulas, invest in research, and put your workforce on the production line. Then open Bram Broker.exe to sell your stock and fulfil delivery contracts with demanding specifications and deadlines.

Your customers have particular tastes. You have a profit margin to consider.

A growing business attracts attention. Yours cannot afford it.

Track resources and Suspicion in Red Ledger, then put BlackBook.exe to work on covert operations, stolen supplies, and infiltrating law enforcement. Balance expansion against exposure: let Suspicion reach its limit, and your company is finished.

Discretion remains our most strongly recommended business practice.

Your company is temporary. Your ambition needn’t be.

Through Shrine.sys, sacrifice your current enterprise to claim permanent perks and give your next company a stronger start. Build, offer, and begin again as your accumulated blood brings you closer to waking the Blood God.

VampOS. Because the Blood God expects results.

VampOS is a vampire management game featuring recurring mature themes. Gameplay contains text- and UI-based references to killing and abducting humans, human trafficking, hypnotizing people into thralls, harvesting and consuming blood, recovering and processing dead bodies, and conducting organized crime.
The game also contains prominent stylized body-horror imagery featuring blood, skulls, flesh-like structures, and occult themes. Violence is generally represented through menus, resource counters, and written operation descriptions rather than animated combat.
