Meet the Construct, the machine that was given too much power. It was created by Legimate Research™ to operate the more mundane tasks in the facility (Cleaning, Object transportation, etc). however, overtime, it proved itself to be exceedingly useful. This persuaded the scientists to give it more and more control over different things, until it gained access to some things it shouldn't have gotten into. The results? The Construct ripped power away from the scientists, took control of the facility, and other cliché evil robot genius stuff. It uses a massive arsenal of circular saws to defend itself.
Due to a request, you can now fight it.
