Autodoors are powered doors that open and close a lot faster than regular doors of the same material.


Autodoors can be be constructed with Stuff 25 Stuff (Metallic/Woody/Stony), Steel 40 Steel, Component 2 Components and 1,100 ticks (18.33 secs) after the autodoor technology has been researched.


The autodoor draws 50 W of power at all times. If not enough power is available or the door breaks down, it behaves exactly like a regular door of the same material.

Contrary to the in-game description, not all autodoors allow unimpeded movement. Actually, a powered autodoor opens at 400% speed. This means that all powered autodoors that are not made of stone indeed do not slow colonists down; move speeds that would be high enough to have an effect in this case are not achievable in practice.[Re-verify] Stone autodoors, however, open only slightly faster than regular wooden doors.

The below animation shows a comparison of different door types and materials (the animals all have the same movement speed of 5 c/s, comparable to a fast human pawn).

Opening speed of various doors. Door materials from top to bottom: stone (manual), no door, steel (auto), wood (auto), stone (auto), steel (manual), wood (manual)


  • Work to build an autodoor is 130% the value of the corresponding regular door.
  • Most other relevant stats (except opening/closing speed) are unchanged from regular doors of the same material.


The value proposition of autodoors must be considered - they cost more than regular doors, a large number of them will burn through your component stocks in breakdowns, and you need to power them. If pawns are not routinely passing through the door, it shouldn't be an autodoor. Generally only very high traffic doors should be converted, and even then they should be compared to a wooden door or a held open door. Since autodoors not only open, but also close fast, they help when a pawn needs to flee from a threat. This means that compared to the regular door, the auto door is more likely to close before the pursuer can step through or block the door. This makes them good choices for main entrances to the base

Material selection is also key. Generally speaking, autodoors are put in positions where their security matters, as otherwise an wooden or open door could be used instead. As such, durability and fire immunity is key alongside opening speed. With 0% flammability, the highest possible HP, and second highest door opening speed, plasteel is therefore the best possible material available but obviously comes at significant expense. While somewhat slower and less durable, uranium also makes for a very cost effective subsitute for the more in-demand plasteel.

Autodoors allow the use of stone where their slow opening speed would otherwise preclude them. In most situations, this is where durability and fire immunity are required, but uranium and plasteel are in short supply. This is not without downsides though - stone autodoors are only slightly faster than (regular) wooden doors risky to use, and in times of power failure they will slow down colonists tremendously. This is especially painful because a blackout situation is very often also an emergency situation, where free movement is important.

  • Styles[edit]

    Ideoligions allow the selection of styles which then change the texture of the certain items and buildings when constructed by the colony. These style variants can be crafted if the colony has the selected style, or can be looted from raiders from factions with the requisite style.
