Jen's comb:
Hit Lo with an attack before you fight him outside of Lo's Cave.
Turtle Stone:
During the fight with Jen (second time) using Li Mu Bai, find the bell and break it.
The Turtle Stone should fall out.
Bonuses:
Successfully complete the game to unlock the mini-games, FMV sequences, movie
sequences, and survival mode.
Film clips:
Successfully complete a level with an "A" rank to unlock a film clip. The ratings
used to determine your rank include: special moves, combo blocking (L), and
continues used. The easiest way to do this is to do specials on Bosses or block a
lot of their moves. Also, watch the health meter. With the survival mode, just play
a New Game Plus until your characters are strong enough.
Alternate endings
You can change the endings by collecting special herbs and by your in-game performance (get "A", "B", "C", etc. ranks).
Combo blocking
Repeatedly press L.
Completing survival mode
Pay attention to your health. Get a weapon quickly. Look for items. There will be a mini-Boss for every 70 or 100 opponents that you defeat. Play a New Game Plus frequently to get a lot of strength. By completing this mode, you will unlock new costumes. Try to use Shu Lien and Mu Bai in this mode.
