Backwards manual is a glitch that may happen in the Next-Gen versions of THPS3 and the THPS4 demo from the PS2 version of Kelly Slater's Pro Surfer. Basically this glitch makes skater to perform manual, but facing backwards. This state doesn't allow to ollie off the ramp. This glitch may happen after 180 degree turn at certain circumstances. The Xbox version of THPS3 and the THPS4 PS2 demo allows turning while backwards manualing while in the other versions you can't turn. This glitch can be fixed by DefMod3.
