The only difficulty of obtaining all the achievements lies in finding someone to play on Xbox Live, and getting two red L powerups in one round to attempt “A Piercing Light.”
Arkanoid is a pretty straightforward game and most of the achievements are as well. There are four episodes, two of which are DLC. The two DLC episodes do not factor into achievements, all of them can be (or must be) obtained in the first two episodes. You will also need a second player/controller for the one local play achievement. An additional playthrough will be required on ONE of the episodes for the same local co-op achievement.
Step #1- Get the Live/vs. achievements out of the way:
There are two of them, and they are not particulary fun. First, if you are lucky enough to find someone who plays online, play some Xbox Live matches. More than likely, you will have to ask in the Achievement Trading thread to play ten matches (win or lose) for “The Real Battle Specialist." Play one round, and lose on purpose ten times. Then, you must WIN 10 matches against the computer, offline. Set the rounds to 1, set the CPU Level to 1, and you should have no problems with “The Mock Battle Specialist.”
Step #2- Just Play! (and then grab a friend if you can):
You get an achievement for clearing Episode 1, and also for Episode 2 in single player. Must be done by yourself. Also, play with a friend (or if you are friendless, plug in a 2nd controller) and replay either chapter for another. Also, there are 4 achievements for progressing/clearing episodes without continues, two for Ep. 1, and two for Ep. 2. Completing the first ten rounds in each episode without continues should be easy. Completing all of the rounds w/ no continues can be tough, but are easier and unlockable with a co-op partner. I personally suggest using max barriers with the ball speed on slow, and of course on Easy difficulty. Barriers remember, reset after each round. So with the two single player episode playthroughs and the one co-op episode playthrough, you are looking at playing a minimum of three episodes.
Along your way, grab a Mini Vaus powerup and destroy 10 blocks, and make sure you have enemies ON to destroy 100 of them for another achievement.
Step #3- A Piercing Light:
This achievement is the most difficult, and sadly involves some chance. Getting a red L powerup lets you shoot blocks, but getting two in a row in one round, lets you shoot through the blocks. For this achievement you have to shoot through 16 blocks with one shot. Some levels don’t even have that many blocks that can be shot at once based off the placement of them or gold blocks in the way. When the opportunity arises, make sure you are ready. Always be on the lookout for the proper placement of blocks, and L powerups. Round six, episode two has been suggested in the Achievement Guide as a good round, but even be ready on Live or versus matches, as it can be done there as well.
Should be an easy 200. If you have troubles with the no continues achievements, make sure to play co-op. A Piercing Light is all about opportunity, so seize it.
