Metal Buildings
Allows building and use of the five metal houses after researching. Requires a level 3 research bench and medium building shells research in order to begin researching Metal Buildings. Cost is set to one Engineering Research.
Buildings:
-Swamp Dome
-Metal Wallhouse
-Swamp House
-Swamp Shack
-Swamp store
Each house is built with iron plates with more needed depending on the building size.
I may divide out the research levels but feel this is fitting for now. May add building materials for the swamp buildings as they do have wooden structure bits.
