About Reactor Labs [ PRE-RELEASE ]
Welcome to Reactor Labs, an experience rarely before seen on Roblox. ⚠️ The game is not meant to run on very low performance devices! Optimization re-works are WIP. - Operate the reactor & turbine, multi-task, and invest in upgrades to make everything (even survival) better. - Compete for speed-run times, published automatically in the community server. - Purchase more turbines & extra reactors to further increase power production, and upgrade them too. - Perform maintenance on the turbine & FW pump with your repair kit, as you will have to. - Repair malfunctions such as a circuit break trip suddenly happening, and importantly, avoid disaster. Keep in mind this game is in PRE-RELEASE. Bugs, glitches and etc CAN appear.
