One input. Two arenas. One gun. Your clones move in perfect lockstep across a split screen, so a wall on either side stops you both and only the clone holding the gun can shoot. Throw it across the divider and keep the swarm off you.
You don't control a character. You control a formation one clone in each arena, moving in perfect lockstep from a single input. Push left and both clones push left. A wall in either arena stops the whole formation, so every route you take is the overlap of two maps at once. Reading both screens is the skill.
There is exactly one weapon between them. Only the clone holding it can shoot; the other is defenceless. Throw the gun across the divider to arm the far side and for the moment it's in the air, nobody can shoot at all. Every fight becomes a running argument about which screen deserves the gun right now.
Clear the waves in both arenas to close a round, then spend your cores in the shop on upgrade cards — ricochet rounds, incendiary shots, split-fire fans, reactive novas. Cards stack. Builds compound fast. Death is permanent and there is no meta progression: every run starts from zero, and the only thing that carries over is what you've learned.
A boss stands every tenth round. The Twins mirror you across both screens with a shared health pool. The Gatekeeper seals each arena behind a wall of shock rings. Survive to the end and the run doesn't stop it keeps going, harder, until you do.
