Sony has released two new Knack trailers showing off the game's co-op mode.
Game director and PS4 lead system architect Mark Cerny has said Sony designed the two player mode to help kids play the family friendly game.
Daniel Brooke, online producer at SCE WWS, elaborated in a post on the PS Blog: "A second player can drop in or drop out at any time, and controls Knack's shiny metallic helper called Robo Knack. Robo Knack has a move set somewhat similar to Knack's, but in addition Robo Knack can donate parts to Knack and heal him with a touch of the Triangle button.
"If you have a non-gamer, or a light gamer in the house, it's a great way to bring them into the world of Knack - just start the game on Easy and drop in from time to time to help them through the game. Plus, if you enjoyed the smack fests in LittleBigPlanet, you'll find some fun and laughs in smacking your on-screen partner when he or she least expects it."
Knack's co-op mode can also be played via Remote Play on Vita.
