Start here
Your first five steps
The starter numbers below are reported in guides updated on September 1–2, 2026. Those dates do not establish when the gameplay was recorded. They are historical references, not live prices.
Mine manually and buy your first Player upgrade
Break nearby blocks for Cash and open the Skill Tree. A September 1–2 guide recorded Damage I at $1 and a three-voxel break. Use the values in your current server.
Add Drone I for automatic mining
A guide updated on September 2 reported Drone I at $5 and described automatic mining. This is a historical source report, not a live price.
Build a mixed setup
Add Player Damage and Mine Speed, then a Turret when its current price is comfortable. Turret I appeared near $23 in the dated route; Mine Distance helps with reach.
React to chests and the Eagle
Chests can appear inside the mountain. Dated PC material showed F and a 50-Gem result. When EAGLE INCOMING! appears, leave the red warning path.
Keep clearing layers, then compare Pickaxes
A guide updated on September 2 reported an 89-layer clear. The cited guides also describe Gems used in the lobby Pickaxe Store. Compare current shop information before buying.
