If you play as Chun-Li, finish the Story Mode with no time limits. When you defeat Seth (Final Boss) in the game, Her story will be featured as an anime movie. When its finish, skip the credits and go to the Arcade Mode if Gen is unlocked.
you have to go on VERY hard mode and do the boosterpack retrieval quest and must kill the boss with one hp. on VERY HARD MODE, note that you CANNOT heal or use a gate disk, even hp skills and mp disks don't work, the only way to cheat through this is by equipping a dread-drain ram and keep attacking with your specified weapon. note that your weapon needs to have one mod at least. when completed. talk to the digi-elf at the terminal area and receive your reward of imperialdramon fighter mode digivolution. the same thing goes for agumon.( to get to 1 hp before the boss, sink yourself in the sand pit at the end and get to the boss, kill it without getting hit.
Yes it does.
