Drill to Earth’s Core is a co-op Roblox descent where up to 30 players share one drilling vehicle and push straight down toward the planet’s center. You scavenge dungeons for loot and fuel, break through boss walls, and upgrade the machine until you reach the core at 100,000 meters. The gap between stalling early and pushing deep comes down to your class, your drill stats, and how you handle each dungeon.
Quick answer: Start as Lucky Looter, spend your first upgrade points on Drill Power (or RPM Overclock if you pay Robux), scrap items you don’t need to unlock modules, and never skip a dungeon.
The core loop that gets you to the core
Everything in a run feeds one repeating cycle. You fuel the drill, break walls, clear the dungeons you pass, defeat their bosses for chests, sell what you gather, and reinvest in upgrades and gear. The drill machine runs mostly on rails, so you only control forward progress while it chews through wall after wall.
To keep moving, feed the furnace. Most items you pick up work as fuel, while the more valuable ones are worth saving to sell at checkpoints. Insert any combustible item into the furnace to refuel, and the machine will destroy the walls ahead. Between dungeons, zombies attack the rig. If your health is high enough you can shrug off the hits and keep drilling, and just before certain checkpoints armed allies open fire to clear enemies for you.
After a set number of layers you reach a checkpoint, a safe rest area where you sell loot, buy gear, and prepare for the next stretch. Restock, then head back out and repeat until you reach the earth’s core.

Pick a class before you start drilling
Classes are permanent archetypes that grant passive bonuses. Head into the Classes building in the lobby and roll for one before your run. The higher a class’s rarity, the stronger it is, so aim for the rarest you can get. For a first run, one pick stands above the rest.
| Class | Why it works |
|---|---|
| Lucky Looter | Best beginner pick; extra loot funds every other upgrade |
| Driller | Raises drill power and damage while lowering upgrade costs |
| Pirate | Solid all-round alternative |
| Reaper | Solid all-round alternative |
Lucky Looter is the strongest starting choice because the extra loot it pulls directly pays for the drill upgrades and gear you need to survive deeper layers. Driller, Pirate, and Reaper hold up well if you want a different feel.
Drill upgrade priority
The shared drill’s numbers are displayed in the upgrade interface. Prioritize attributes that help you break walls, then give the supporting stats only modest early investment instead of making them your main targets.
| Upgrade | When to prioritize |
|---|---|
| Drill Power | First priority for free-to-play players |
| RPM Overclock | Top priority if you spend Robux |
| Drive Speed | Useful early, don’t over-invest |
| Engine Overload | Useful early, don’t over-invest |
| Sack Storage | Useful early, don’t over-invest |
| Deadly Drill | Highly valuable later; damages enemies on contact |
Drive Speed, Engine Overload, and Sack Storage make the first layers easier, yet prioritizing them over Drill Power can leave you unable to break the harder walls where many new players get stuck. Once you descend farther and enemies hit harder, move your focus to Deadly Drill.
Turn junk into scrap to unlock modules
Convert anything you do not intend to use into scrap instead of letting it take up inventory space. This currency pays for utility modules that add vehicle functions, including Autopilot, Advanced Drill Boosts, Sentries, and Gem Refineries.
Clear every dungeon and fight bosses at range
Treat dungeons as required stops rather than optional side trips. Their layout is consistent: first comes a compact area to explore and loot, then a boss room split into two phases. Enemies fill the first phase, and the route opens only after you defeat them; the second puts you against the boss, which has more health and more powerful attacks. Victory awards several chests. Avoiding these encounters leaves your drill too weak for the walls farther down.
A server can include 30 players, so form a team with people who can revive you and contribute their dungeon clears. That makes the deeper walls much easier to handle.
Earn Coins and gear up at trade outposts
Selling dungeon loot is how you earn Coins. With the cursor aimed at nothing, press F to remove an item from your bag. Then, while holding nothing, use the left mouse button to drag it onto the sell station. After the item leaves your bag, its value appears beneath its name.
Use those Coins at the trade post found inside every checkpoint. Its gear selection includes Swords and Armor, and every item has an individual stock probability that you can inspect before purchasing. The inventory updates every few minutes, allowing higher-rarity gear to show up. Consumables and healing items follow the same system, with a separate stock chance for each one.
- Armor for durability
- Dynamite for clearing obstacles and enemies
- Healing supplies to survive longer runs
- The Rifle, the recommended weapon
The Rifle pairs naturally with the range-first approach to bosses, so buying it early makes every dungeon safer. Keep the loop tight, refill armor, healing, and ammo at each rest stop, and the drill stays strong enough to carry the whole team down to the 100,000 meter core. Reaching a new checkpoint, collecting boss chests, and watching the depth counter climb are your signs that the run is on track.
Is it free to play?
Yes. The game includes premium options that speed up progression, but you never have to touch them to finish a run, so it stays fully free to play. Focus on the loot-clear-upgrade cycle, keep the machine fueled, and every layer becomes a step closer to the earth’s core.
