Rocket jumping


In first-person shooter games, rocket jumping is the technique of using the explosion of an explosive weapon, most often a rocket launcher, to launch the shooter. The aim of this technique is to reach heights and distances that standard character movement cannot achieve. Although the origin of rocket jumping is unclear, its usage was popularized by Quake.
Rocket jumping is used often in competitive play, where it can allow the player to gain quick bursts of speed, reach normally unobtainable heights, secure positional advantages, or in speedrunning. However, a potential consequence of rocket jumping is that it can injure the player, either from the blast or from fall damage. This effect makes the technique less useful in games where the damage from the blast and/or fall is high, or where health is difficult to replenish. Rocket jumping from standing is impractical in real life, and would be certainly fatal if attempted. However, Ejection seats from an aircraft are, in effect, a combination of a seated rocket jump and a parachute.

In the Quake series

While using explosives to propel oneself was first seen in Doom, the modern technique became a core mechanic in Quake, taking the technique to literal new heights. By exploiting the physics of the Quake engine, many advanced movement techniques were spawned: such as circle jumping, strafing, bunny hopping, and, of course, explosive jumping. The community quickly became accustomed to using these various methods of gaining speed, and so was born the first speedrunning community. Rocket jumping was kept as an intentional mechanic for the leading games in the Quake series. In some of the computer-controlled opponents use rocket jumps.

Forms

Rocket jumping has appeared in several games in a variety of forms, sometimes as a form of emergent gameplay.

Horizontal

A horizontal form of rocket jumping appears in Doom, where it is used to reach the secret exit in E3M6.

Vertical

The first games to feature vertical rocket jumping were Bungie's Marathon and 3D Realms' Rise of the Triad. It was featured as well the same year on The Outfoxies, an arcade 2D platform versus game released by NAMCO. The character Betty Doe can be seen performing one in the attract mode, so it might be the first time it was depicted as such. Rocket jumping became very popular in the original Quake, and was used as an advanced technique for deathmatch play as well as for the Quake done Quick series.
In the game Team Fortress 2, players can use the explosive knockback of the Soldier's rockets to rocket jump. Rocket jumping in Team Fortress 2 is a crucial skill required for players playing the Soldier class in high level play, especially to quickly move back to the next map objective after respawning. The Demoman also has sticky bombs and grenades, which can be used to do a similar strategy called sticky jumping. The Soldier and Demoman also have unlockable non-lethal weapons that allow them to rocket jump or sticky jump without taking blast damage. The Pyro class can also do a similar, but limited form of rocket jumping using their "Detonator" or "Scorch Shot" weapons.Pyro's secondary weapon, the Thermal Thruster, is a jetpack that contains 2 charges that can blast the Pyro in a similar manner to a rocket jump. The Pyro can also reflect the Soldier and Demoman's explosives, allowing them to rocket jump too. Lastly, the Engineer can use their Sentry Gun and Wrangler once at level 3, to rocket jump by right clicking while aiming at the ground to fire 4 rockets. Engineer can also use the Gunslinger and Wrangler to do a semi jump with "bullet jumping" as the mini-sentry's bullets damage the player.
In Overwatch, multiple characters have explosive projectiles that can be used to rocket jump.
Rocket jumps are a mechanic in the 2D platformer Butcher.

Other variations

Rocket jumping has appeared in other media as well.
