Overview
It all started when Grandpa lost the keys to his old Soviet car somewhere in the yard. Armed with a shovel, you're now digging a proper Russian hole—deeper and deeper. Unearth valuable resources, upgrade your gear, level up your skills, and unlock new underground secrets. Who knows what lies beneath familiar soil? Just don’t forget why you started: without his keys, Grandpa’s not a legend—he’s just a grumpy old man!
