The wall jump is a common term for the ability of a video game character to kick off of a wall to gain a bit of height. This technique is most common to platforming games, but can have its place in other genres. Usually, the character will jump between two parallel walls, but it is possible in some games to do a wall jump at a 90 degree corner. The most interesting thing about this is that it is technically possible. The trick relies on applying force on the wall and using momentum in order to push yourself up. Video game wall jumps are a bit less demanding on momentum, but nearly always show the character pushing off against a wall. It's interesting to see something some consider only possible in games done similarly in real life!
