This mod is loosely based on We Need To Go Deeper by Sirus and LetsGoDeeper by Test-Account666. What was missing from those mods for me were some randomness and more configuration options. That's my original reason for making this mod.
Everyone in the lobby should have this mod installed for it to work properly. I also suggest using the same configs to be safe.
Whenever you land on a moon there will be a chance for the facility's entrance control systems to become active (default 1/5). If this happens there are three possible situations that can occur:
Normal mode (default 4/10): In this mode you can only enter through the main entrance and leave through a fire exit
Dynamic mode (default 5/10): There is a separate chance for the systems to go into dynamic mode. If this happens then everyone can enter using any door they want. Each player can then only leave using the type of door they did not use to enter. If you teleport inside using the Inverse Teleporter then you can exit through any type of door. This mode has priority over both other modes
Corruption mode (default 1/10): If dynamic mode did not activate then there is still a chance for the systems to be corrupted. In this case you will have to enter using a fire exit and leave through the main entrance, flipping normal mode on its head. This can be very gamebreaking due to locked doors inside the facility blocking your path. This mode has priority over normal mode
You will get a message at the start of the moon telling you about the state of the entrance control systems for that day
