Ultor-issue miner envirosuit.

Envirosuits are specialized suits, mostly issued by the Ultor Corporation, necessary to venture out into caves without life support, underwater or on the surface of Mars.

These suits become redundant when the Earth Defence Force arrives on the red planet, finishing off Ultor in the First Martian Revolution.[1] The EDF begin their terraforming initiative and construct the Terraformer, allowing colonists to breath and live on the Martian surface. However, many of colonists had kept as a reminder to honouring those that have sacrificing themselves for freedom.[2]
