Stalcraft Wiki: Reaper Jumpsuit

In-game description (EXBO)

Although some bandits consider it "shameful" to hunt artifacts themselves instead of "jumping rookies," most still copy stalkers by adopting their arthunting practices. Baron smelled profit and moved fast, providing the bandits with their own suit by making minor modifications to the Uranus units purchased from Research Institute 7.
