WELCOME BACK, PUPPIES

The ‘Shell System’ allows you to command a roster of up to three unique bodies, switching between them instantly during the fight. Rather than being locked into a single class for a hundred hours, you build a roster. Each ‘Shell’ is different: distinct playstyle, abilities, and a different role in the slaughter.

KILLER COLLABORATIONS

Combat in Rengkok is a high-speed puzzle: reflexes keep you alive, and strategy keeps you winning. Knowing when to swap and what to chain will make the difference. You will chain skills across your ‘Shells’ to build combat loops that compound with every rotation. The same rules apply whether you're running a solo or teaming up with three players in co-op.

NEW TOYS

Every piece of salvaged tech is a step toward survival or a step too far. Outfit your ‘Shells’ with weapons, protective gear, and internal implants, but every item draws from that Shell's resources. There are no free slots, only trade-offs. Push your gear further with crafting, and the stakes and risks go higher with every attempt.

SAME PUPPY, NEW TRICKS

Every Shell in your roster features a deep, specialized progression path. You get four skills with branching nodes that change how those skills behave. The deeper you go, the more variations and combinations you can unlock.

When you finally discover that perfect setup and start landing devastating combos, it’ll feel personal.

Become something Rengkok didn’t plan for.
