Fruit Ninja Kinect

I didn't have a second person to play with, so I used Arcade Mode. Start getting combos (3 or more fruit at a time.) The more combos that you get, the more the banana power ups appear. I combined a Frenzy with a Freeze and swiped my arms collectively across the screen. You can work on this at the same time as the Dripping With Power (Slice 30 bananas in arcade mode) achievement.

This achievement requires you to get a ten fruit combo. I don't believe you have to equip anything specific, but some people have reported you have to equip the Calligraphy Brush, Ink Shadow, and Parchment background, so you might as well do it just in case.

To do the achievement, go to Party Mode -> Team Arcade. If you don't have a second person just use a jacket or something to trick the game so you can swipe ready. I had a stand lamp that I hung a hanger with a jacket on. It looked like a person sort-of and tricked the game enough. Then I reached around it and used my arm to swipe. It takes a bit of messing about but eventually I got it. Then just knock yourself out. After my first 10 fruit combo the achievement unlocked.

Contrary to other comments, this has not been patched (I just unlocked it on 2/23/12)

Here’s a solution with all requirements. Equip the Calligraphy Brush, Ink Shadow and Parchment background. Go to Party Mode, then Team Arcade. Trick the Kinect into thinking you have a second player next to you with a jacket or something more human looking. It took me a few minutes of going in and out of camera range with my jacket buddy but it eventually worked. You basically have to swipe Ready with your hand and then flail the jacket arms around to swipe Ready for the “second player”. You’ll notice that your swipe is red, whereas your dummy player’s swipe is blue. So if it swipes red with the jacket/object, it’s still only reading you as one player. After it starts the game, drop the jacket and get a 10 fruit combo, most easily done during a freeze or frenzy. Then pop goes the achievement!

It’s also worth mentioning that your equipped items might not show up during a party game. However it is required that you equip them in the dojo prior to playing. Those requirements only show up in the 360 achievements menu. I can confirm that playing without equipping these items first prevents a 10 fruit combo from unlocking the achievement.
