Isaac Clarke did not exactly set our worlds on fire in the recent Dead Space 3. However, this engineer has impressed us in another way; through a stunning cosplay of his trademark suit.
Showing off his custom-made suit (complete with Stabilizer, Plasma Cutter, and Ellie sidekick), cosplayer tarrer (Kevin Leab Thong) created his RIG from scratch over the course of a few months. Since then, he has made appearances at the Japan Expo in Paris.
You can find his DeviantArt (and some WIP pictures) on his page here.
