FAQ

Coolant questions

What do you actually do in a shift?

Department of Energy players keep the reactor making power and complete power orders. Plant defense holds the facility against raiders. West Noobian and allied hostile teams try to break that power supply. The official description also turns on double XP during weekends.

Which job can a new account join immediately?

Plant Maintenance, Plant Security, and the West Noobian Assault Force are the documented free starts at 0 XP. Reactor Operations sits behind Plant Maintenance and then Logistical Operations, unless you buy the Reactor Operations gamepass.

What temperature should Reactor Operations hold?

The community reactor guide uses 1,420 K with control rods at 55 percent when fuel is above about 75 percent. Hazard Pay, if that policy is active, pays extra above 2,100 K and pays less below it. Meltdown warnings start at 3,120 K. The cold floor is 323 K.

Where is the code box?

Open the settings cog or the three-bar menu in the upper right, choose Codes, paste the string, and press Redeem. Type the published capitalization. A rejection can mean the account already used it, the string was retired, or public lists disagree.

What did the 30 October 2026 notice add?

The Roblox description for that date announces a zombie event, 2NIA event teams, and a quests system. It also says a new code is planned at 70,000 likes. That sentence does not publish the code string.
