An experimental gear prototype created by Scientific Research Institute 7 specifically for its operatives performing tasks in heavily contaminated areas. The design of Ganymede went in parallel with the work on Antares. However, due to a group of engineers who disappeared in the summer of 2025, the further development process was delayed. This allowed them to use knowledge of unsuccessful decisions in the design of another suit to their advantage. As a result, the engineers managed to better optimize the exoskeleton's performance and devise a more precise design, ideally suited for work in anomalous zones and the collection of various samples.
