Crouching Tiger, Hidden Dragon - Completing survival mode

Completion 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.

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.

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.
