rocket jumping. The Demoman class can achieve a similar effect using his own assortment of explosive weapons. It is also possible to use knockback provided by enemy explosives to perform a similarly boosted jump as any class. In Overwatch (2016), multiple characters have explosive projectiles that can be used to rocket jump. In Minecraft (2011), the player can activate TNT in order to propel themselves more quickly. While it is usually fatal when attempted, equipping armour can render most damage useless. It can also be attempted with creepers, in-game entities that explode upon close contact. Other variations A similar technique can often be performed with other explosives, such as grenades, remotely detonated bombs or explosive objects in the level; depending on the game, these might be more, equally or less viable alternatives to rocket jumps. Some games offer weapons that knock the user back with their recoil. In the Unreal series of games, in addition to traditional rocket jumps, the weapons can be charged up for a powerful melee attack that can be aimed at the ground to boost the player. In Half-Life (1998), the tau cannon can be charged for a stronger attack that pushes the user back; in the multiplayer mode of the game, the weapon charges up faster, and the knockback is increased to a point where it can also be directed vertically, allowing players to use this as a form of mobility. In the Halo game franchise, players often use guns such as the Concussion rifle or Frag grenades to launch the player faster or higher for speedrunning purposes, or to reach normally unreachable areas or easter eggs. In Fortnite Battle Royale it is possible to ride launched missiles to reach other places that are time-consuming, difficult or impossible to access on foot, provided that the rider safely disembarks at a nearby platform before the missile explodes. This technique, called rocket riding, does not follow the typical definition of rocket jumping (in that it does not leverage the force of a rocket explosion), but can be seen to be related to it in that it inherits its risks. Outside video games Rocket jumping has appeared in other media as well. In the live-action film Transformers, the character Ironhide performs a rocket jump over a screaming woman after transforming from his truck mode. In the film Planet Terror, lead character Cherry Darling uses her false leg, a
