First Timer Trophy in Chaos Code
Finish STORY MODE at difficulty "4"
How to unlock First Timer
You must clear story mode with default settings - difficulty 4, 2 rounds, 99 seconds per round. The final boss, Kudlak, will be rather tricky until you have learned some basic combos with your character of choice, but your basic strategy is to NEVER allow him to keep you away because he will outrange you to death. Stay up close (using moves with limited invulnerabilty, moving supers, or the A+B roll), and keep comboing him until he goes down. You are allowed to continue, which helps.
