I made this in Unreal Engine using Megascans for all of the terrain. I made the props in Modo, Marmoset Toolbag and Substance Painter. The design of the mech is from Maschinen Krieger the other props are my own design. I created the soundtrack in Ableton Live and brought all of this into Adobe Premiere to make final edits to everything.
