This is Lee Houlgate, a cosplayer and cosplay constructor living in the UK, he wants to build the awesomest StarCraft marine mech suit cosplay known to man. The suit itself will be an impressive 8' feet tall and for some perspective, the gun alone is 5' feet in length.
He plans on having this steel / aluminium suit built to the hilt with robotics that increases his strength, NERF gun weaponry (for blasting), and all the gadgets and gizmos any space marine would have or ever need. If you are interested in helping him out, check out his kickstarter project to see more.
Thanks go to Rosemary Darkshines for the hot tip on this badass project.
