About this game
Hamstr Protocol is a first-person bio-mining simulator. You mine HAM - a digital currency powered not by electricity, but by hamsters.
Build your own hamster-powered mining operation and turn a small setup into a thriving bio-mining empire.
ASSEMBLE
Experience tactile, first-person interaction. Pick up, carry, and place every piece of hardware by hand. Every component matters in your quest for the ultimate mining setup.
SCALE
The more you scale, the harder it gets to keep everything under control. Manage heat, noise, and hunger as you expand your underground facility into a massive bio-mining network.
LIQUIDATE
Money never sleeps. Use your in-game ATM to track market trends and trade your HAM for USD at the terminal. Reinvest your profits to break the system or save up for the next big upgrade.
CORE FEATURES
Hamster-powered rigs - Mount runners on wheels and attach high-end GPUs.
Thermal management - Heat is your biggest enemy. Cool your rigs or lose your hardware.
Tactile Management - A deep first-person simulation where you handle every asset manually.
Virtual Ecosystem - Manage your entire operation through a fully functional in-game PC.
Something doesn't add up - But that's a problem for later.
