This move is similar to the Triangle Jump, except the user can move vertically rather than just horizontally along walls, thus allowing the user to ascend the walls by springing between them and reach higher routes in a stage.
When in an area that allows Wall Jump, the user can jump onto the nearby wall and hang onto it, but will slide down the wall they hang onto until they reach the bottom if they hang onto it for too long. When there are two facing walls in close proximity to each other, the user can jump off the wall they hang on to, and over to the opposite wall while going higher up, then set off again with a new jump etc., thereby scaling the narrow space until they reach the top.
The Wall Jump first appeared in Knuckles' Chaotix and was only usable by Mighty the Armadillo. Once Mighty jumps against a wall, press the C button to grab onto the wall and scale it by pressing Up at the D-pad and the C button to jump.
The Wall Jump returned in Sonic Unleashed as one of the moves used by Sonic the Hedgehog. In order for Sonic to use the Wall Jump in the PS3/Xbox 360 version of this game, he must have obtained the upgrade called the Wall Jump Shoes. When finding an area where Wall Jump is required (which is usually marked by the position of the Rings) Sonic will instantly grab onto the wall, and can scale the walls with jumps by pressing /X on the PS3/PS2/Xbox 360 version and on the Wii version.
The Wall Jump made a reappearance in Sonic Colors as one of Sonic's standard moves. The move's mechanics and controls are identical to those presented in the Wii version of Sonic Unleashed though he can only perform it in the 2D side-scrolling sections of stages.
The Wall Jump returned again in Sonic Generations, as one of Modern Sonic's standard moves. In this game, the areas where Wall Jump is possible is marked with red and black plates, with arrows that covers the walls. However the player cannot perform the move in areas without markings. If Modern Sonic is equipped with the Skill called "Direct Jump", Modern Sonic will perform the Wall Jump much faster. The mechanics and controls are identical to Sonic Unleashed.
Sonic Lost World
The Wall Jump reappears in the Nintendo 3DS version of Sonic Lost World, and it functions much like it previously has in the past Sonic the Hedgehog games. Note that he can only use this technique while in the 2D-side-scrolling zones of Sonic Lost World.
