The Adventures of Tintin The Secret of the Unicorn - The Game

You fight Red Rackham in one of Captain Haddock's "ancestor's memories". He's quite easy to fight. Simply parry and counter, and you should beat him simply. I'm not sure if you could use Kinect is story mode, but I'd imagine this being easier with Kinect (for the challenges). However, I don't have Kinect, and fought through this part with the standard controller.

The thugs around Rackham are easy to kill. Just move both your LS and RS forward randomly, and you're bound to take them out.

For Rackham, press A to hold a defensive stance, and observe his attacking patterns. If he moves his sword upwards, this means he's doing a downward slash. Hold A and hold RS horizontally. This will parry his attack, and leave him momentarily dazed. Follow up with a LS attack forward quickly, and you'll damage him. If he does a left or right slash, this means he's doing a sideward slash at you. Hold A and hold RS vertically. You'll parry him, and can counter his as above.

There will be a few instances where you'd need to do the above. Just do the hold A, parry and counter move, and soon you'd defeat him for the achievement.
