Denmark-based prop builders Daniel Høgh and Justina Šniukštait of Roses and Boltshells spent over 2 months creating this incredibly detailed Imperial Fists Terminator Captain costume out of foam. It is based on the real-time strategy video game, Warhammer 40,000. You can view more photos of the costume on deviantART.
Here are a few videos from Daniel Høgh showing the massive costume in action.
