If you've played the original Knack (the joke is on you!! All 60 million+ PS4 owners have!!), then you know the original co-op mode was pretty much a joke. Your partner could barely take any damage before dying and it didn't add much to the overall gameplay.
Knack II? The co-op gameplay looks pretty damn sweet! Here's a 22 minute video Sony showed-off live at Ani-com & Games Hong Kong featuring a flurry of co-op gameplay for your eyes to feast upon.
I'm pretty sure if you're a fan of the original game, you know Knack II releases on September 5 in the US and on September 6 in the UK for $39.99/ £29.99.
Will you join in on the Knack Attack, Brah?
