Introduction:
Welcome to PJ Masks Power Heroes: Mighty Alliance, the second PJ Mask game on console, and another that follows pretty much the exact same format as the first one. This is a 2D platformer with lots of collectibles, but with no way to die or lose, making it a very easy game. There are four areas, each with five levels and a boss fight. The boss fights are simply Quick Time Events that are impossible to fail as well. There is therefore no real difficulty with this game or the completion (it's meant for kids, after all). Let's get started.

Abbreviated Walkthrough:
While you can breeze through all levels no problem, there are a few things to look out for:
 

• Every level (including the boss levels) has two masks to collect. These are typically all pointed out in secret areas with arrows with question marks on them, making them pretty easy to spot. On vehicle levels, the game shows the mask coming up and approximately where it'll be, so just pay attention. You need to collect every mask in the game
• Every regular 2D platforming level has a gift box (this is what the game and achievements refer to as "collectibles") to find. Once again, these are almost always in secret areas that are easy to spot. You need to collect every gift box in the game
• There are tons of gems in all levels. There are only two achievements related to gems: one for finding everything in a level (all gems, masks, and gift boxes), and one for finding a cumulative total of 6500 gems. The former will likely come naturally in the first level you play, and the latter should come naturally as well. I unlocked it by the end of the second (of four) areas, so there is plenty of leeway considering every level has at least 400, but sometimes upwards of 1000, gems to collect. Once you get those two achievements, feel free to ignore all gems from then on

Considering virtually every mask and gift box (in the 2D levels, anyway) is in a secret area, you'll unavoidably unlock the achievements for secret areas relatively early in the game.

The second type of miscellaneous achievements are related to enemies. Specifically, each of the first three areas has a specific type of enemy (moths in the first area, ninjalinos in the second, and robots in the third). You need to defeat a set amount of each enemy type, and you will assuredly do this naturally as you progress since there are tons of enemies in this game. There is also an achievement for defeating each enemy type, which will happen naturally while going for the cumulative enemy achievements. Lastly, there is an achievement for jumping on enemy heads 20 times. There is no reason to do this aside from the achievement, because doing so doesn't even defeat enemies. It's easiest to do this on the robots in the third area since they're stationary, so take care of that then.

The last miscellaneous achievements are for destroying boxes and going through accelerators. These two achievements should also come naturally as you progress. There are dozens of boxes per level, so you should hit 350 by the end of the second area if you're destroying them. Once you unlock that cumulative achievement, feel free to ignore all boxes after that. Same goes for the accelerators, which are only present in the vehicle levels. There are many in every driving level, so you'll likely hit 50 by the end of the second area. Once you're done with them, there's no need to use them anymore other than to speed up the time it takes to complete a level.

So, to sum up, once you get the miscellaneous achievements out of the way relatively early, all you need in every level is the masks and the gift box. Everything else (boxes, gems, enemies, etc.) can be ignored. Beat the game and you should have the completion. If not, use the level select screen to see what levels you're missing anything in, and replay them to mop up what you missed.

Conclusion:
This game is virtually identical to the first, but with more characters to play as and many more levels. It's the same simplistic collectathon as the first game, so for any normal gamers playing this, expect a relatively short and simple slog through repetative levels to get collectibles. Congrats on another easy completion!
