Want to run a glowing gun store in the future? Like Recettear and Moonlighter, Neon Blight is split between shop management and action-RPG adventures. To get new stock to sell to gun nuts, you need to go out and find guns, most of them seemingly from the corpses of fallen enemies.

It’s in early development, but you can download the alpha from Itch.io. There’s not much to it right now, though. The shop management stuff isn’t present and the town only has one NPC, but you can head out into the forest and relentlessly murder people with guns. The forest is an odd setting that doesn’t exactly scream cyberpunk. That said, maybe the genre needs a bit more greenery.
