SNKRX is a fast-paced arcade shooter with roguelite elements where you command a snake-like chain of heroes. Each hero has their own distinctive attacks, passive abilities, and class traits, and they automatically engage enemies when in range as your snake continuously moves. Drawing inspiration from the auto-battler genre, the game encourages strategic mixing of heroes: lining up characters of the same class can unlock powerful combined bonuses, while purchasing duplicate heroes from the shop lets you upgrade them for even stronger performance.
