Doors and Traps

Learn how to use doors and traps strategically in Core Keeper, including locking mechanics and placement tips.

All doors share the same properties. Each type of door is progressively stronger and more resistant to enemy attacks before it breaches. You can use a door to separate rooms or to keep opponents out of an area for a little while.

Putting a trap just in front of or behind a door (like a Boulder trap!) can be a very strategic thing to do.

To lock a door, hover over it with your cursor and click on it. If successful, a small key icon will be depicted over the door, signifying that none of your creatures will attempt to pass through it. This can be useful for restricting creatures from entering certain areas.

Warning: Doors have sale values, but a glitch prevents a gold value from appearing when you sell them. Keeping track of the actual gold counter shows how much they are actually worth.
