"On a planet far from Helios's main base, an employee had started constructed a large facility. Since he had kept his boss in the dark about this, he named it Helios Dark, where he brought a renaissance of guns originally deemed unusable against living, human targets due to their sheer brutality, but were brought back to rip apart the zombies terrorizing the Trans-Fed system. These guns were based mostly on previously released guns from older manufacturers, dating back to 2358, for example, in the case of the Helios 3-334. As of 3505 Helios DE is owned by Kaizen Corp. after Helios DE forces surrendered during a war."
