Corner Boosting is an exploit that is the result of a buggy interaction between Wall Jumps and map geometry, allowing players to gain significantly more height than a standard wall jump. This technique can be performed on any edge, corner or curved surface but requires precise positioning and timing.
When you attempt to Wall Jump, the game will check the closest point on the wall from your collision capsule to determine your launch angle and vector. When near the edge of a horizontal and vertical surface or on a curved surface, the resulting angle, and therefore vector, can become incredibly steep, and (after addition with other vectors) result in an incredibly steep resulting vector. This is further helped with the shape of the collision capsule and its rounded shape, allowing for even higher angles. This results in a Wall Jump with near to no horizontal velocity (depending on the surface) and incredibly high vertical velocity.

This is a illustrative diagram that shows the game calculations behind the behaviour of Corner Boosting.
- fig. 1. shows a normal Wall Jump. Since the surface is a normal vertical wall, the push vector is angled 90°. Combined with the other set vectors (a set sideways vector and a set upwards vector, which normally make you ascend in a normal Wall Jump), this creates a slightly upward angled final vector, in which you travel in.
- fig. 2. shows a Corner Boost. Since the surface being Wall Jumped off is angled upwards, the resulting angle and therefore vector is angled accordingly. This vector is added to other set vectors to create a steep final vector, in which you travel in.
Corner Boosting has several practical uses:
- It grants extremely high height, which can be very useful for traversal around the map. Corner Boosts can be used to scale buildings or escape enemy pressure on the ground.
- An example scenario is Corner Boosting off a fence railing and using Heavy Melee Cancel to escape into a building roof.
- Corner Boosting can provide an advantage in combat. This is especially useful for
Lash, whose Ground Slam gains damage depending on the height when used. - The height gained from a Corner Boost can allow you to peek over obstacles (e.g., bridges, barrels) for better sightlines.
- Certain characters who have abilities that require sightlines to properly work benefit greatly (e.g.
Vindicta's Assassinate, 
Bebop's Hook)
Corner Boosting works on all surfaces to varying extents; edges of a horizontal and vertical plane are best and provide the most vertical distance, but curved surfaces (e.g. Midboss Roof, Golden Idol statues, Hotdog Stand) can provide a near optimal Corner Boost as well.
