Welcome to Boom Ball 3 for Kinect, the third in a series of Kinect games where you use your hands as paddles in a BrickBreaker/Arkanoid-type game in order to destroy all of the blocks on screen. As far as Kinect games go, this one is pretty simple but pretty engaging. However, simple does not mean easy. Depending on your skill, this could be quite a tough completion, as there are 50 levels and you need to get gold medals on all of them. This can lead to a lot of frustration when trying to make precision shots with your hands via the Kinect, so expect to put a decent amount of time and effort into this completion. Let's get started.
This completion is relatively straightforward, and can essentially be broken down into the following three tasks:
- Get a gold medal on all 50 levels
- Complete all 50 levels without losing a ball
- Complete all levels on at least Fast difficulty (this is necessary to unlock all paddles), with 10 levels being on Turbo difficulty
For the first ten levels:
- Start by playing each one on Normal difficulty first, and attempt to complete it without losing a ball.
- Immediately replay each level on Turbo difficulty to beat it on that setting. Don't worry if you lose a ball or anything else, just try to beat the levels
- Most likely, beating a level on Turbo difficulty will unavoidably be fast enough to get a gold medal simply because the ball moves so fast. If you beat it on Turbo and don't get a gold medal, replay it on Fast difficulty. This will feel much more manageable after Turbo difficulty, but will still be fast enough to be able to get a gold medal
- Start by playing them on Fast difficulty. After the first ten levels on Turbo, Fast shouldn't feel bad at all. Try to complete the level quickly, aiming for a gold medal. Replay the level on Fast until you get a gold medal
- If you lost a ball during your playthrough(s) above for a gold medal, replay the level on Normal difficulty, focusing only on ensuring you don't lose your ball. Time doesn't matter at all here. This should feel very easy on Normal after playing on higher difficulties
You will very likely unlock all miscellaneous achievements naturally along the way aside from Power of Two (50G). If you're missing any others, refer to their solutions in the guide below to see where best to unlock them. As for Power of Two (50G), while it does imply you need a second person, it actually does not require it. The solution has more information, but if you can find a second person to help, it'll be much easier than trying to do it yourself. Once you wrap up the miscellaneous achievements, that should wrap up this completion.
After playing many Kinect games, I can confidently say that Boom Ball 3 is one of the most frustrating I've ever played. So many glaring issues with hit detection that make this game more aggravating than fun. The entire thing feels like a slog from start to finish through every level. Hopefully you get more enjoyment out of this game than I did (since I got almost zero), but preferably don't even bother buying it, as it's primarily an exercise in frustation and patience more than an enjoyable Kinect game.
