The Twin Tech Harpoon is an unused piece of Twin Tech from Crash Bandicoot: Evolution. It is apparently a weapon piloted by the Ants, but its true purpose is unclear. Its main weapon appears to be a harpoon, thus giving it its name as it appears in concept art. There is a door present below it, but it is unknown how its pilots would enter, considering the harpoon is floating off the ground. The Twin Tech Harpoon appears in only one piece of concept art, so little is known about its use, location, or purpose.
