WIP. Biters now drop Chitin-bearing Shell Fragments. Process Shell Fragments into Chitin slurry, extract, and waste product that must be disposed of. Spoiled fragments will spawn biters nearby just as eggs do. Use Chitin to make durable and regenerative walls, unique equipment for fighting modded biters, and consumables. Requires GZ-Hazardous Materials. GZ-Threat is also recommended.
