Mission 46: Collect hearts

Mission 46 in Kingdom Hearts 358/2 Days sends Roxas and Demyx to collect hearts at Olympus Coliseum.

Summary
Team up with Demyx, eliminate Heartless in Olympus Coliseum, and collect hearts.

Objectives

 * Defeat Heartless and collect hearts!
 * Smack barrels into the Heartless to defeat them!

Story summary
Roxas and Demyx team up together and go to Olympus Coliseum. Once Roxas defeats the Heartless outside, Demyx will stay outside to "finish off the Heartless outside". Roxas walks into The Coliseum to see Phil training Hercules. After their training is done, Phil will ask Roxas to train again.

Mission walkthrough
You will start outside as usual and immediately get confronted by two Jumbo Cannons and two Ice Cannons. After you finish them off, Demyx will leave you alone, and so your training with Phil will be solo as usual.

And again, it's time to collect hearts! As usual, the training is hitting barrels into the Heartless; this time it is Loudmouths on platforms of various heights. Be careful hitting barrels; they can appear on any platform, sometimes making it easier to hit other barrels than the Loudmouths! You have 1:30 to defeat as many as you can, and as usual, the darker brown explosive barrels can be a great help.

As before, you have three attempts; you should reach the regular goal just fine with one, and should get 100% with a little work in the other two. Once you finish, you may leave through the dark corridor.
