Here's how Knack's two-player co-op works
PS4 launch title Knack will feature local co-op support, allowing another player to jump in and control titular hero Knack's companion and helper, Robo Knack. Using a DualShock 4 controller or Remote Play through a PS Vita, this second player can use Robo Knack to pummel baddies or support Knack by hooking him up with spare parts - basically health - when he's running low.
Knack, which is developed by Sony's Japan Studio and directed by PS4 architect Mark Cerny, will be available at the PS4's launch on November 15. The action-platformer centers around a Katamari-like creature known as Knack, who grows in size as he gathers objects known as Relics.
