Step 1 - 1st Playthrough
Start a new game and select Challenging as the difficulty. This is the hardest difficulty in the game, but apart from a few boss fights it is not that challenging, especially if playing in two player co-op.
Whenever your character dies during the game, the system automatically switches control to one of the other playable characters. You can then walk up to the KO’d character and then revive him/her by pressing . This coupled with some generous checkpoints makes dying not as annoying as other games.
Whilst playing though each level keep an eye out for any collectable stone fragments. These are needed to complete various Super Hero Feats (trackable via the pause menu). Unfortunately you will not be able to collect every single fragment during this playthrough, as some areas are only accessible with certain characters. You will need to play Free Play Episodes to finish collecting everything.
Step 2 – 2nd Playthrough (Free Play)
Whilst in your headquarters to the right of the screen you will see a computer terminal, from here you can access the free play Episodes.
You will need to play through all the Episodes again, this time though you will have access to all the super heroes you have used during the main story, so you should be able to access any secret areas previously inaccessible.
If when you are doing freefall sections, you are able to pause the game and restart the checkpoint any time you wish. The game saves every time you collect an item, so once collected the item is saved even if you restart checkpoints.
You will also want to complete all Hero Feats whilst playing through this section. Check the individual trophies for descriptions of each Feat.
Step 3 – Challenge Mode
The final step in the game is to complete all the challenges within challenge mode.
Some of these challenges can be very very annoying, but with patience you should have no problem completing each challenge. I found that some of these challenges were easier to complete if you use 2 players rather than attempting it on your own.
The reason this step is left until last, is because you unlock new challenges whilst playing through the game and completing Heroic Feats.
