About To The Core
To The Core is an incremental adventure where you drill into planets across the solar system, extracting resources to fuel deeper excavations. Each planet presents stronger material, urging you to gather upgrades that boost drill durability, fuel capacity, and damage. The game runs in single‑player mode and supports family sharing on Windows. Resources you collect improve automatically as you mine them, creating a mastery loop that rewards repeated extraction.
01 / THE GUIDE
Core Gameplay Loop
You select a planet, drill until fuel depletes, and collect the extracted resources. Those resources then fund upgrades that let you drill farther on the next planet. The loop repeats across the solar system, with each world offering tougher material that tests your upgraded drill and fuel management.
- Observe how fuel consumption scales with drill depth before committing to a planet.
- Compare the resource yields of nearby planets to prioritize efficient drilling.
02 / THE GUIDE
Planet Progression
Planets are arranged from easier to harder, each providing stronger resources than the previous. Traveling farther requires better upgrades to survive the increased difficulty. Choosing the right planet at each stage balances risk and reward, as stronger planets yield more valuable materials but consume more fuel.
- Test a planet’s resource type before fully committing to gauge fuel needs.
- Plan a route that minimizes back‑tracking to conserve fuel.

03 / THE GUIDE
Automatic Resource Mastery
Every mined resource has a built‑in mastery system: the more you extract, the greater the buffs applied to that resource. This creates a scaling benefit for repeated mining of the same material. Mastery effects are expressed as percentage improvements, such as increased drop rates, encouraging focused extraction strategies.
- Focus on a single resource to unlock its mastery bonuses faster.
- Track which resources have already reached high mastery before switching.
04 / THE GUIDE
Upgrade System
Collected resources can be spent to improve drill durability, fuel reserves, damage output, and to add quirky upgrades. These upgrades directly affect how far and how efficiently you can drill. Upgrades are purchased as needed, allowing you to tailor your drill to the challenges of upcoming planets.
- Prioritize fuel upgrades early to extend drilling sessions.
- Balance durability and damage upgrades to avoid premature drill failure.
05 / THE GUIDE
Mastery Bonus Example
A concrete illustration of mastery: mining 100 units of iron grants a 5 % increase to its drop rate. This demonstrates how repeated extraction translates into measurable benefits. Such examples help players understand the tangible impact of the mastery system on resource collection.
- Track iron mining milestones to anticipate the 5 % boost.
- Use the iron bonus as a benchmark for other resources.
