Volcano Skip

Cave Skip is a skip in Jak 3 that allows Jak to enter the Monk Temple earlier than intended. Doing so allows Jak to trigger the Find Oracle in Monk Temple mission earlier than intended, resulting in a percentage warp.

Technical

There are several versions of volcano skip the most simple being the one used in the Any% category at the beginning of Temple Skip. In the starting area of the temple during the mission Climb Monk Temple Tower there is a decorative pillar along the rock wall of the mountain that lacks collision at the top. Runners clip through this gap after bouncing on a trampoline and boosting themselves up with the Wave Cuncussor then navigate out of bounds around the door that normally blocks the player from entering the temple until completing Find satellite in volcano.

In previous routes of the Any%_No_OoB category however we had to do a more complicated series of steps to achieve the same end goal. Jak ignores collision while he is getting off a ledge in his target-edge-grab-off state but to take advantage of this and clip through the temple door we need to get the dune hopper vehicle inside of the temple. The developers wanted to make sure you couldn't just simple drive the car into the temple presumably because upon entering it the desert would deload and despawn the vehicle. To prevent the player from doing this they added a gigantic wall of vehicle blocking collision in front of the entrance. This wall is just barely able to be bypassed via careful platforming along the rocks on the left side of the level with the dune hoppers jumps assisted with carefully controlled boosts to help position and angle the vehicles momentum in the air. Once the car was over the wall runners would then drive it to the entrance of the Climb Monk Temple Tower mission and exit the vehicle. Once on foot runners then readied a double stacked Wave Cuncussor shot to push the Dune Hopper inside the temple. Runners then entered the temple and started the cutscene for the Climb Monk Temple Tower mission, this cutscene moves jak over near the entrance to the temple bypassing the camera based trigger that deloads the desert and despawns the car in normal gameplay. After skipping the cutscene runners could then drive the car and position the back boost exhaust port slightly infront of the temple door leaving a small gap jak could enter and get a ledge grab. Then runners could hold back on their stick and press x to get off the ledge and briefly ignore the doors collision while in the target-edge-grab-off state and entering the temple early without leaving the bounds of the level.
