The blood of ancient warriors boils in your veins! Once you step on the planet - there is no turning back! Delve deep into underground facilities overflowing with gold and silver, but be warned: your quest will not be easy. You are outnumbered 1000:1, and the enemy will spare no ammunition. Prepare to face overwhelming swarms and dodge thousands of projectiles in your fight for the ultimate loot! The deeper you go, the deadlier the tech used against you. Defenders will climb walls, place mines, flood you - even tank will be tasked with your elimination. Your high-tech blaster requires a live connection to your ground station. Every wall blocks your signal, and if the connection drops, your gun stalls. Without a signal, your blaster is useless—and a shovel is your only weapon! Strategically place signal repeaters and forge your path through a deep tech tree. Calculate optimal combinations to unlock unique boosts. Repeaters are everything: they provide your damage buffs, health, ammunition, and line of sight.
