The research laboratory (also called Arlings' laboratory) is alongside the passage tunnel the only building in the Toxic Swamp Sector. Unlike other buildings, there's a transport beam that can be used to enter it. It is the main base of Reckoners in A.I.M. 2 Clan Wars and the source of most Reckoner-based missions, making it an essential part of A.I.M. 2's story. It is also the only building where mushrooms can be sold for a solid price.
