Reactor Relay
A Roblox experience owned by SP1 Studios.
Description (written by the developer; not a statement by this register)
One player sees the unstable reactor. Everyone else sees the handbook. Communicate clearly, solve strange systems, and keep the reactor from going critical. Play with 2–6 friends across randomized missions, escalating difficulty, recurring emergencies, strikes, timers, and dozens of module combinations. Can your crew keep talking long enough to keep the reactor stable?
