Rocket Jumping has become a common occurrence in first person shooters. The idea is that detonating an explosive at your feet will allow your character to move much faster in exchange for damaging yourself. In Team Fortress 2, a cartoony class-based first person shooter by Valve, about 4 of the 9 classes have some way of "explosive" jumping, but today I'll be talking about the Rocket Launcher-wielding Soldier. One of the main characteristics of this class involves movement through the air using rocket jumping. The problem is the damage. I'm sure you realize that any sort of explosion could be fatal to a normal human being. However, in Team Fortress 2, a weapon exists that acts the same as a Rocket Launcher, but does no damage. This weapon is called the Rocket Jumper, for obvious reasons. Realistically, if an explosive had the force to knock you into the air, the force alone would be enough to kill you. Not to mention the other classes' forms of jumping, such as grenade launchers, flare guns, rocket-shooting sentry turrets, and defying gravity by jumping in the air up to 5 times.
