Core Keeper Map Guide

#Direct Answer

Open the full map with its configured control—M by default on keyboard—then pan and zoom to inspect the areas you have explored. Use player markers to record specific tasks such as an unmined tin boulder, a working drill rig, or a boss approach. A marker is a note; an activated waypoint is a travel object. Placing a marker does not create a teleport destination or reveal an unexplored biome.

The official 1.3.0.1 notes added custom hover text, ten color variants per icon, and four new marker icons. Older screenshots showing only the earlier marker choices do not describe the full interface for that version and later.

#Read The Map Before Extending A Tunnel

Zoom out to see how your known routes connect, then zoom in to check the next crossing or return lane. Dark unexplored areas are not proof that a boss or biome is absent. Your map reflects what has been revealed, not a complete preview of every scene in the seed.

Use the Core and established routes as anchors. A branch that enters stone may be useful for iron even if the current task is tin. Mark the transition and return to clay rather than extending a stone tunnel indefinitely. The Map reference covers the interface, while the World reference supplies generation context.

#Place Markers That Tell You What To Do

On keyboard and mouse, select a marker preset in the map interface and use the displayed placement action on the intended location. Use the preset's customization menu for icon, color, and hover text. In the 1.3 interface, right-clicking a preset opens its customization controls; the official 1.3.0.3 notes mention right-clicking the same preset again to close that menu. If using a controller or remapped bindings, follow the displayed action prompts.

Choose a small personal legend and keep it consistent. The game does not force the example below:

Avoid relying on color alone; combine icon and text so nearby markers remain distinguishable. Update “no drill” when a rig starts operating and remove a depleted-boulder note when the job ends.

#Markers, Scanners, Waypoints, And Portals Are Different

Use the Cartography Table reference for co-op sharing. Have each player interact as needed to contribute and read map information; do not assume merely joining a server gives every player an identical personal map.

#A Concrete Example: Search For Tin And Get Home

1. Mark where a known tunnel first enters clay and label it “clay entry.”
2. Explore a short branch through fresh clay, checking ore deposits instead of following only the farthest tunnel.
3. If the branch enters stone, mark “iron route” and turn back to the clay entry for the next tin branch.
4. Mark a tin boulder “no drill” rather than spending the whole trip trying to mine it with a pickaxe.
5. Return through the known entry, smelt the ore, and change that marker only after you actually install a working rig.

This is an editorial search example, not a seed coordinate or a recorded expedition. Its advantage is preserving the next action after a break: the map tells you whether you need mining tools, a drill, a summon, or simply an empty inventory.

#Why A Seed Video May Not Match Your World

The official 1.0 launch notes introduced new generation and world settings. They also warn that non-boss dungeons and custom scenes may differ even when the same seed is used. Compare generation version and settings before treating a coordinate from another player as a guarantee.

Older explored terrain also preserves world history. A new patch affecting generation does not prove every already revealed area was replaced. Search and mark your own world rather than overwriting the interpretation of your map with an incompatible screenshot.

#Troubleshoot Controls And Travel

If the map will not pan with expected keyboard bindings or controller marker prompts look wrong, check the installed patch and controls. The official 1.3.0.3 notes fixed map panning bindings and marker customization issues.

If a newly available waypoint or Portal cannot be used immediately, check activation rather than adding another map marker. The 1.3.0.1 notes reduced activation time, so an older guide's fixed wait is not a safe current value. This page intentionally does not repeat an unverified timer.

#Check The Return Before Departing

Mark a departure point you can identify, a destination with a named task, and a return cue visible from the far end of the trip. Repair equipment, pack healing and food, and leave inventory space for the target. Confirm that any intended Waypoint or Portal is actually available; a player marker alone does not create travel access. If the route changes, update the one failed cue before extending the next branch.

#FAQ

#Can I teleport to a marker?

No. Use an available travel destination such as a waypoint or Portal. A placed icon is only a map note.

#Does the same seed guarantee the same dungeon coordinates?

No. Version, settings, and the official limitation on custom scenes matter. Record the source's setup before trying to reproduce it.

#Should I mark every ore deposit?

Usually not. Mark locations with a future action, especially boulders and machine sites. A used-up small deposit rarely needs a permanent note.

#Sources And Review Notes

Official 1.3.0.1 and 1.3.0.3 notes support marker customization, control changes, and activation-time cautions; official 1.0 notes support generation limitations. Community Map and Cartography Table references give further interface context. The marker legend and tin trip are editorial examples, reviewed November 10, 2026 without a new controller or co-op test.
