Completion bonuses
Successfully complete the game to unlock the credits, all FMV sequences, hard difficulty setting, high score screen, opening demo, and stage selection options. Note: Additionally, you can select the saved game file used to complete the game to play again with all previously collected Tai Chi symbols, upgrades, orbs, magic, and other bonuses.
Defeating Overlords
On Hard and Extreme (and even later stages in Normal), Lau Wong will need to defeat Overlords quickly instead of spending time clashing. The most damaging combo is the SQUARE, SQUARE ... TRIANGLE, X combo which racks upwards of 40+ hits. If you press SELECT to change your spell to Tekkuken (the attack up spell) as you begin the combo on an Overlord, you can probably kill it in one combo (or at least rip off half its life). Similarly, you can use this technique on bosses as well. Select the defense up spell when you are clashing (or as you are being hit) to prolong your effectiveness against harder bosses.
Extended Glide
On Hard and Extreme, Lau Wong will need to cross very large gaps in some stages without benefit of an Iron Soul Mirror (which you can usually air-combo to get across). After gliding, press TRIANGLE to do the spin slash, then press X to glide a subsequent time. You can repeat this over and over to cross large gaps, but you lose altitude each time you press TRIANGLE.

Prolong Combo Timer
The combo hits can be made to linger on screen if you have Lau strike an object like a jar or sign. Although the hit does not count as a combo hit, it will prevent the combo chain from breaking so you have a short time to find another enemy to continue adding hits.
