The purpose for the blast door corner is to allow the passage between blocks without damaging them. Two of its sides have half a meter of space between it and its neighboring block. The angled narrow edges also allows it to slide smoothly against other blocks. This in turn allows for the creation of doors mechanically controlled by rotors and/or pistons that can slide next to other blocks without any damage occurring.


Blast door blocks are similar to armor blocks, however have a narrow corner profile and smaller collision box so not to damage surrounding blocks. These can be used in conjunction with pistons for example to create a large functioning door.

The blast door has been made mostly obsolete by the Airtight Hangar Door.

  • All blast door blocks currently have no deformation enabled, meaning they will stay the same shape till they are completely destroyed
  • Since blast doors have a gap and pistons are never airtight, a room with a blast door leading to space is impossible to pressurize.
