The apparatus was a vital part of the upkeep of the facility's nuclear reactor - and you just took it out.
With the facility meltdown mod the appartus has a lot more risk (and reward) attached to it. When you take it out the entire facility spirals into a self destruction sequence! You'll have 2 minutes to escape and take off before you get vaporized.
FacilityMeltdown will work with most custom moons and all interiors.
This is known and comes from modded moon creators not setting up in the exact way that vanilla moons are setup (which is fine). They will need to add explict support as it's not something I can really fix on my end. If you're a moon creator and this issue is happening to you, ask in my thread on the modded lethal company discord how to add support!
If you are strugling with playing the mod have a look at the bottom of this readme to find some useful tips and tricks. Or you can modify certain things in the config.
Music and voice lines come from portal 2. I love portal 2.
FacilityMeltdown itself doesn't support custom music. However, this tutorial made by "platinumbin" on Discord shows you how to use the PizzaTowerEscapeMusic mod to add custom music. Link to tutorial: https://www.youtube.com/watch?v=D5hKkSLlEhk
loaforcsSoundAPI is a mod I built specfically for the LR team. There is a template avaliable here, otherwise read the getting started wiki. This tool is still in development and I recommened using PizzaTowerEscapeMusic for now However this comes with the added bonus of being able to use Meltdown's dynamic system of speeding up the warning voice sounds as the meltdown occurs.
All game balance options are synced (only the host needs to edit them, but it wont hurt to have everyone using the same config). Visual and Audio settings are independent of what is synced.
lethalconfig or lethalsettings will let you edit the settings in-game.
