I'd never considered the prospect that some people might cheat at playing Helldivers 2. But I suppose it's inevitable given some people will find ways to cheat at anything. In this case, rogue Helldivers have found ways to game super credits—the premium currency used to buy Warbonds—to earn them at impossible rates, and it's become such a problem that Arrowhead has implemented new ways to tackle it.
"You've told us that cheaters and exploiters ruin the experience that it feels unfair when someone games the super credit system while you're out there earning yours the hard way," Arrowhead wrote in a Steam post. "We heard you, and we're starting to implement changes that will tackle issues like this."
