Molten Sublevel Research Laboratory
A Roblox experience owned by ROBLOX STUDIOS BUILT!.
Description (written by the developer; not a statement by this register)
Welcome to Molten Sublevel Research Lab! An underground scientific research facility powered by a nuclear reactor. There are various teams you can be such as scientists, security, medics, firefighters, and if you want to get chaotic... you can even be a member of the Chaos Agency Units and destroy the facility. The facility can be destroyed by melting the reactor beyond safe temperatures. This will trigger a meltdown which will eventually result in the complete self destruction of the reactor. This is a "secret" underground facility where experiments are made. The facility is powered by a fusion reactor which you better keep at temperatures below 3000C or it will go unstable and explode.

Growth
Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
