EvilSlayer plunges you into a bleak, post-apocalyptic world overrun by a mysterious disease that turns humans into ravenous monsters. As one of the last survivors, you’ll join resistance cells determined to halt this ever-spreading horror. The game’s core loop is simple but addictive: dive into frantic bullet-hell encounters, unleash devastating attacks on wave after wave of mutated creatures, and then retreat to your stronghold once your stamina (HP) is depleted.
