Drill to Earth's Core Wiki

Classes are the roles players pick in the lobby before a run, such as mining, drill upgrades, healing or fighting. Each one comes with starting gear and passive bonuses built around its job. Players buy them with Cores, a separate currency from Coins, through the class shop in the lobby, where the selection rotates. Classes level up through goals reached during runs, and a class's fourth level unlocks a team bonus.

Drill upgrades are the purchasable boosts that improve your drill in Drill to Earth's Core, covering damage, speed, storage and survival. They range from Common to Mythic and are bought at the Trading Post with Coins earned by selling loot. Drill Power is the best first pick for most players.

Drill to Earth's Core is split into layers, starting with the grass at the surface and running down to the Heart of the Earth. Each layer brings tougher blocks, new enemies and hazards, and it ends in a boss wall that must be broken before the next layer opens. A normal run ends at the 100 km wall, and Infinite Mode carries the digging on to 1,000 km.

Enemies in Drill to Earth's Core start as goblins near the surface and become mutated monsters, dungeon bosses and special threats the deeper you dig. Mutations make regular enemies tougher, faster or more valuable, while boss walls stand between you and each new layer. Fuel Leeches, Bombo and the Watcher can drain fuel, disrupt your drill or kill on contact, and bounty miners carry bounties worth chasing.

Items in Drill to Earth's Core include ores and gems, coal and other fuel, melee and ranged weapons, pickaxes, armor, healing items, consumables, scrap, relics and loot from dungeons and enemies. Coal keeps the drill running, iron and gold ore can be smelted into bars, and loot sold at the Trading Post turns into Coins. Scrap can be recycled at Crazy Zack's Crafting Shack into scrap points for utility modules, and relic shards reroll passive bonuses.

Dungeons and structures are the side areas you pass as your drill heads toward the core. Dungeons are enemy-filled rooms that end in a boss and several chests, and they're one of the main places to collect fuel and loot. Other structures include the Mineshaft, the Vampire Mansion, the Goblin Arena, and spider tunnels, while Rest Stops, Trading Posts, and Churches support the trip.

Enemy mutations are changes that can appear on monsters as you dig deeper in Drill to Earth's Core. They begin in the Stone Layer at about 10 km, and most layers after that bring a new one. Some make enemies tougher, faster, or slower, while Toxic, Fire, and Frozen hurt or slow you when they hit. Most also make an enemy worth more when you sell it or burn it for fuel. Golden comes from the Money Fog and a Gunsmith perk.

Chests are the main source of Cores and gear in Drill to Earth's Core. The tiers are Wooden, Golden, Diamond and Void, and higher tiers pay out more Cores as you go deeper. You can buy chests in the lobby shop or find them in dungeons, including as boss rewards. Wooden chests can turn into Mimics when opened.
