The Jetpack is a rare and immensely helpful accessory for traversing the caves.
It is most commonly found for sale in a Shop, either as a regular purchase or inside a Mystery Box, and can also appear as a very rare drop from crates, or by breaking the wall behind the Alien Lord in the UFO Crash Site level of the Ice Caves.
As with all items, it may also be found buried in random walls, visible only with the Spectacles or Udjat Eye. Finally, it will be gifted by Kali after an Altar sacrifice at the appropriate favor, but only if all other items that Kali can gift are already possessed by the player.
The jetpack cannot be equipped at the same time as a Cape or Vlad's Cape; picking one up will automatically drop the other if you have it. As with other worn items, the jetpack is not lost when the player dies and is resurrected by the Ankh, unless the jetpack was crushed along with the player.
The jetpack has a base value of $18,000, which then increases by an increment of $2,000 per level, meaning that with a minimum shop value of $20,000 it is the game's most expensive item besides the Ankh.
The Jetpack cannot be taken off apart from equipping a Cape, though it's possible to get rid of the Jetpack if the player has the Ankh by teleporting into a wall (a thin wall, so the Jetpack drops instead of getting crushed) or being eaten by a mantrap.
The jetpack simply allows the wearer to fly in any direction by pressing the jump button in mid-air. Not only is this very useful for exploring areas of the game's levels that would be difficult to reach otherwise, but it is also invaluable when attempting to lure the Ghost into the path of gems (commonly known as Ghostrunning) due to the degree of control that it offers when the Spelunker is airborne.
The jetpack runs out of fuel as it is used. If fuel runs out during flight, the user will fall out of the air. The fuel replenishes immediately when the spelunker touches the ground, grab a ledge, grab a rope, or grab a wall with the climbing gloves. However, it does not recharge by jumping on an enemy or landing on a Web or the Worm's tongue.
Flying with a single continuous boost produces the quickest acceleration, but boosting in short 'hops' will allow one to fly substantially further before running out of fuel.
The maximum height reachable with a single jetpack boost is high enough to cause fall damage if the user lands on or below the level you took off from; be careful when flying upwards if there is no ledge in sight on which to land. This is especially dangerous in when over spikes, lava, or The Abyss.
The jetpack will instantly explode like a bomb if crushed. Pushing one against a wall with a block or the Shield or being stomped on by Olmec while wearing one are examples of this. Unlike its incantation in Spelunky 2, the jetpack does not explode if it or its user is hit by fire based attacks.
The jetpack is even one of the few items (along with the Scepter) that does not melt in Lava, because of this, it's possible to throw a jetpack into the lava of Olmec's Lair and drain the lava by making Olmec fall on the jetpack (which will explode the floor at the bottom that holds the lava).
- Ropes can be used to kill enemies attacking from above. This can be especially useful during an Olmec fight, or to free yourself from Monkeys robbing you. A rope can also be useful to recharge the jetpack in mid-air if there are no blocks around.
- The Cape, as well as ropes, let spelunkers safely descend on spikes without getting impaled. The jetpack does not allow this.
- The Climbing Gloves allow the player to remain fixed in one position against a wall without running out of fuel. This can be useful for aligning the ghost during ghostrunning or to recharge the fuel.
