Back in 2014 Bushlurker sent me his "Island 51" a terrain builder test 51km terrain. To my knowledge it was never released publicly.     Now with the incredibly sad passing of Bushlurker I decided to put this terrain out there as tribute to him. I only added mod.cpp with Bushlurkers info and packed it, otherwise this is the original addon I received from him.   No addons required. Terrain created completely in L3DT (what he told me, referring to satellite texture/mask). To me the terrain looks great and whats best, its huge 51km x 51km.   Download 823mb torrent from PMC Tactical ArmA 3 Downloads. Mirror: google drive.
