Sony Japan Studio's PS4 launch title has co-op, a feature that hasn't been trumpeted too much - until now.
On a post on the PlayStation Blog, Sony's Nick Accordino wrote a blog and posted a trailer that details the game's drop-in, drop-out co-op mode.
Accordino writes, "In Knack, our two-player cooperative mode was designed in a way that accentuates the vision for the game. A second player can drop in or out at any time, and control Knack's shiny metallic helper, Robo Knack. Robo Knack has a move set somewhat similar to Knack's, but can donate parts to Knack and heal him with a touch of the Triangle button. If there's a non-gamer or light gamer in the house, this is a great way to introduce them to the world of Knack - just start the game on Easy and drop in from time to time to help them through the game."
