Core Keeper: Complete Biome Exploration & World Map Guide
Master the vast underground world of Core Keeper with comprehensive guides to all biomes, mapping techniques, exploration strategies, and hidden secrets. Navigate efficiently and discover every resource location in your mining adventures!
World Structure Overview
Core Keeper's underground world is procedurally generated but follows consistent biome placement patterns. Understanding these patterns is key to efficient exploration and resource acquisition.
World Generation Principles
🎯 Central Starting Area
Every world begins with a safe central area containing the Core and basic resources. This is your home base for initial exploration.
🌀 Concentric Biome Rings
Biomes are arranged in rings around the center, with difficulty increasing as you move outward from the Core.
🗺️ Procedural Variation
While biome order is consistent, exact layouts, cave structures, and resource placements vary with each world seed.
🔗 Connecting Pathways
Natural tunnels and cave systems connect biomes, but you can also dig your own passages for faster travel.

Advanced Biome: Azeos' Wilderness
Environment Overview
Azeos' Wilderness is a magical biome filled with glowing plants, floating islands, and crystalline structures. This is where you'll find the rarest resources and face significant challenges.
Key Sub-Regions
- Crystal Forests: Dense areas of glowing crystals. Rich in gemstones but guarded by crystal golems.
- Floating Islands: Suspended landmasses connected by bridges or requiring flight. Contain unique resources.
- Ancient Gardens: Overgrown with magical plants. Source of rare alchemical ingredients.
- Scarlet Veins: Deep trenches filled with scarlet ore. Extremely dangerous but essential for end-game gear.
Mapping & Navigation Systems
Mapping Tools & Techniques
🗺️ Basic Mapping
Use torches, signs, and colored blocks to mark paths and important locations manually.
📡 Advanced Cartography
Craft mapping tables, compasses, and GPS devices for automated map creation.
💾 Digital Mapping
Use in-game mapping software or external tools to create detailed world maps.
🎨 Marking Systems
Establish color-coded marking systems for different resource types and danger levels.
Effective Marking Conventions
- Red: Danger areas, enemy nests, boss locations
- Green: Safe zones, base locations, farming areas
- Blue: Water sources, fishing spots, underwater resources
- Yellow: Resource clusters, mining sites, ore deposits
- Purple: Magic areas, enchantment spots, rare materials
- White: Unexplored boundaries, mapping progress indicators
Exploration Equipment
Essential Exploration Gear
| Equipment | Purpose | Crafting Requirements | Exploration Tier |
|---|---|---|---|

Secret Areas & Hidden Content
Common Hidden Location Types
🚪 Hidden Passages
False walls, breakable blocks, or illusionary barriers that conceal secret rooms.
🔑 Locked Chambers
Rooms requiring specific keys, boss defeats, or puzzle solutions to access.
🌀 Puzzle Rooms
Challenges requiring specific item combinations, timing, or pattern recognition.
💎 Resource Caches
Carefully hidden stashes of valuable materials, often behind environmental puzzles.
Discovery Techniques
- Wall Testing: Mine suspicious wall sections that look different
- Pattern Recognition: Look for unusual block arrangements or symmetry
- Sound Cues: Listen for hidden water, machinery, or creature sounds
- Light Analysis: Check for light sources behind thin walls
- Map Analysis: Unexplored gaps on your map may indicate hidden areas
Danger Management
Environmental Hazards
💥 Cave-Ins
Unsupported ceilings may collapse. Use support beams and avoid mining directly upward.
🌊 Flooding
Breaking into water pockets can flood tunnels. Have drainage plans and water pumps ready.
🔥 Gas Pockets
Flammable or toxic gases in certain areas. Use ventilation and gas detection equipment.
❄️ Temperature Extremes
Some biomes have extreme cold or heat. Wear appropriate clothing and bring temperature regulators.
Multiplayer Exploration Coordination
Team Exploration Strategies
- Scouting Parties: Small teams exploring different directions simultaneously
- Base Camp Network: Establish forward bases in each major biome
- Resource Specialization: Assign team members to focus on specific resource types
- Mapping Collaboration:
- Mapping Collaboration: Shared mapping systems with coordinated marking conventions
- Emergency Response: Designated rescue teams for exploring party emergencies
Communication Systems
- Radio Networks: Craft walkie-talkies for long-distance communication

Biome-Specific Exploration Tips
For Each Major Biome
Dirt & Clay Biomes: Focus on establishing infrastructure. Create wide, well-lit tunnels with clear marking systems. These areas will become your main transportation network.
Stone Cavities: Prioritize vertical exploration. Many valuable resources are found at different depth levels. Create staircases and elevator systems for efficient access.
Hive Biome: Move cautiously and methodically. Bees become more aggressive if provoked. Consider creating beekeeping areas for sustainable honey production.
Azeos' Wilderness: Plan expeditions carefully. Bring ample supplies, backup equipment, and escape routes. The rewards are great but the dangers are significant.

Troubleshooting Exploration Issues
❌ Getting Lost Frequently
Improve marking systems, use consistent tunnel designs, craft navigation tools, create detailed maps.
⚡ Running Out of Supplies
Establish supply caches along exploration routes, use portable crafting stations, plan expeditions with adequate resources.
🔄 Inefficient Exploration Patterns
Adopt systematic exploration methods (spiral, grid, radial), use scout drones if available, prioritize high-value areas.
💎 Missing Hidden Areas
Use detection equipment, pay attention to environmental clues, revisit areas with new tools, consult community maps.
Pro Tip: Always carry mapping supplies (torches, signs, markers) on every expedition. Consistent marking and documentation will save you countless hours of backtracking and rediscovery!
