"Gravity Jump" While at the beginning of a jump press the R button followed immediately by the L button. This technique is really useful when jumping over areas that require gravity shifting. "Landing Strike" This move is a bit of a rarity, seeing how it is almost never used. The landing strike technique can be used when Kat lands after a high jump, preferably the gravity jump. The best way to master this technique is to notice when Kat lands. As stated above press the SQUARE button after Kat reaches the ground in the landing slide she does. Infinite use is possible if one masters the gravity jump.
