Wait a second or two for the map to load completely, even though there is a loading screen. Arrow keys to move. Not mobile friendly. Press E for punch. Use punches to knock out guards. This is a prototype for a mission called, "The Cure." You have been instructed to find the cure for Tera's disease in a hidden base, and you will steal it.
