Unlockable: Jet on Sky Missions 
Complete the Free Mission at Shinjuku, after completing Chapter Thirteen. Once 
the Free Mission is completed, a Jet will be unlocked that can be used during Sky 
Missions. 

To select the Jet, scroll all the way down on the Dragon Select menu (past the 
Chaos Dragon) and you'll find a "???" option. Select it, and in the mission you'll be 
flying the Jet. 

Safely Charge Run 
When playing as Caim, find a wall or an obstruction that you can run against. 
Running against the wall will charge your run up. Then, you can execute a run 
attack or get where you need to more quickly.
