Steel grating has an inherent bonus to cleanliness due to most dust and detritus falling cleanly through the grate. Some additions exhibit special qualities.
The last addition, sensor panel flooring, becomes constructable upon completing a new research project: 'Reactive Flooring.'
Upon completing the Machining research requirement access to chainlink fencing, high security fencing, the security barrier, steel grate flooring, and metal panel flooring is made available. Plywood paneling and the simple wood fence are available from the beginning and are relatively simple to construct. Fences are gathered into their own menu category and research requirements have been applied where appropriate. This mod adds 4 new styles of flooring and 4 fences (3 perimeter fences and a smaller defensive barrier). ***Updated to v1.21! Balance pass initiated in response to community feedback!***
