{{滿意工廠模板:Quote|Jetpacks allow for maneuverability and can act as shock-dampeners when out pioneering in uncharted territories. Be sure to keep it stocked with fuel at all times, especially in mid-air!|Caterina Parks's assistant [[Steve]]}}
The '''Jetpack''' is equipment [[pioneer]]s can use to maneuver in the air, gain elevation and avoid [[fall damage]].

== Obtaining ==
=== Crafting ===
{{滿意工廠模板:Recipes producing|BP_EquipmentDescriptorJetPack_C}}

=== Creature loot ===
A [[Jetpack Hog]] drops a single Jetpack on death. As one can spawn at any stage in the game, it allows a Jetpack to be obtained before [[Tier 6|Tier 5]] and used as soon as in [[Tier 2]], when {{滿意工廠模板:ItemLink|Solid Biofuel}} becomes available.

== Usage ==
=== Equipment ===
[[File:噴射背包選擇優先燃料_背包.webp|thumb|A Jetpack equipped in the back slot in the [[Inventory]]]]
The Jetpack is a personal flight device that is equipped. It is used to increase altitude and potentially avoid fall damage. It also increases mobility during jumps, making the directional keys move the player faster than they would normally.

=== Controls ===
You hold down {{滿意工廠模板:Key|Space}} (Jump) key to burn Jetpack Fuel to increase in altitude. You release {{滿意工廠模板:Key|Space}} (Jump) key to descend.

To prevent fall damage, simply tap {{滿意工廠模板:Key|Space}} (Jump) just before the pioneer reaches the ground. This will consume a small amount of fuel.

When flying horizontally, it is advised to tap {{滿意工廠模板:Key|Space}} (Jump) once in a while at the correct timing, instead of simply holding down the {{滿意工廠模板:Key|Space}} (Jump) key. This will allows the pioneer to perform a series of smaller jumps in the air, which greatly increases the flight range.

The (especially horizontal) speed of the pioneer in the air is based on the speed the pioneer had while taking off, so, if the pioneer was running on a [[Conveyor Belt|Mk.6 Conveyor Belt]] before taking off, the flight speed would be greatly increased. This can also be taken to the extreme using a [[Hypertube cannon]] to traverse the entire map if built correctly.

=== Fuel ===
[[File:噴射背包選擇優先燃料_介面.webp|thumb|Preferred Fuel Type UI]]
[[File:1.0版噴射背包各燃料高度.webp|thumb|The height that can be reached with each fuel type  (no tapping)]]
The Jetpack requires fuel in the pioneer's inventory to operate. A fuel bar is displayed at the lower left of the HUD. It quickly depletes during the flight. Refueling happens automatically when the pioneer is standing on a solid surface (not in the air), swimming, climbing a [[Ladder]], or while [[Zipline|ziplining]], consuming the selected fuel from the inventory.

The Jetpack can use any of the fuels listed below. In the Inventory {{滿意工廠模板:Key|Tab}}, a preferred fuel type can be set by clicking the gear icon ⚙️ while the Jetpack is equipped in the back slot.

The preferred fuel will be used first if available. Otherwise, any other fuel in the order visible in the preferred fuel type UI is used.<ref name="yt-9jDBEpAlS2s-1">[https://www.youtube.com/watch?v=9jDBEpAlS2s&t=604s YouTube - Update 8 Quality Of Life Features will blow your MIND - Jetpack Preferred Fuel Priority Order]</ref>

Each fuel type has different properties:<ref name="yt-9jDBEpAlS2s-2">Jetpack Fuel Types and their performance spreadsheet https://docs.google.com/spreadsheets/d/e/2PACX-1vRpBpAqnobvGfzv1Va4dkL3QkUBqivjOSGgc69A-26I0DHpmpijzmr-YfepDptphDXuDvA2CChs335I/pubhtml</ref>

<nowiki>**</nowiki> = Heights achieved holding down the jump button. NOTE: spamming jump button will almost double height gained but is fairly inconsistent.

*{{滿意工廠模板:ItemLink|Solid Biofuel}} is the only fuel available before Tier 5/6. It allows the Jetpack to be used earlier, such as when just getting started with Oil Processing, or when one is obtained from a [[Jetpack Hog]]. It is overall the worst fuel, having slow acceleration and the shortest burn time, and itself cannot be fully automated.
*{{滿意工廠模板:ItemLink|Packaged Fuel}} is the default fuel. It has an average acceleration and burn time, and can be automated easily. However, it is inferior to the following fuel types:
*{{滿意工廠模板:ItemLink|Packaged Turbofuel}} has faster acceleration and improved air mobility, which makes it ideal to use during [[combat]], especially against [[Cliff Hog]]s and [[Stinger|Elite Stingers]]. It takes some additional resources to be automated, but the gains make it worthwhile.
*{{滿意工廠模板:ItemLink|Packaged Liquid Biofuel}} has the same acceleration as Packaged Fuel, but lasts much longer, allowing it to traverse greater distances and go higher than even Packaged Turbofuel. This makes it an ideal all-round and exploration fuel. Its only downside is that it cannot be fully automated, much like Solid Biofuel.

=== AWESOME Sink ===
{{滿意工廠模板:Sinkusage|BP_EquipmentDescriptorJetPack_C}}

== Current issues ==
* During autosave, the Jetpack will continue adding upward velocity during the short freeze that sometimes occurs, causing a sudden upward boost when the game unfreezes that can greatly exceed the Jetpack's normal abilities for increasing altitude.

== Tips ==
* For routinely crossing large distances, it is best combined with a [[Tutorial:Hypertube cannon|Hyper Tube cannon]].
* The [[Tilted Jump Pad]] also boosts the flight range of the Jetpack.
* The Jetpack is complementary to the [[Hoverpack]], which can be used in [[power]]ed areas.

== History ==
* [[Patch 1.0]]:
** Now unlocked at [[Tier 5]] - Jetpack
** Changed AWESOME Sink value from 49580 to 16580
** Default recipe
*** Changed recipe craft steps from 15 to 30 seconds
*** Changed cost from 50 Plastic, 50 Rubber, 15 Circuit Board and 5 Motor to 5 Motor, 10 Steel Pipe, 25 Iron Plate and 50 Wire
* [[Patch 0.8.2.9]]: Fixed a bug where [[Packaged Liquid Biofuel]] could not be selected in the Jetpack until [[Packaged Turbofuel]] is unlocked
* [[Patch 0.8.2.3]]: Fixed Jetpack ({{滿意工廠模板:Key|Space}}) getting stuck
* [[Patch 0.8.2.0]]: Fixed multiple Jetpack UI bugs
* [[Patch 0.8.0.3]]: Minor updates to the descriptions of the Jetpack and Fuels to match the new Jetpack changes
* [[Patch 0.8.0.0]]:
** Jetpack can now refuel while the player is on a Zipline.
** The Jetpack can now use a selection of fuels with different burn rates and acceleration. Thanks to this the Jetpack can be used before automating fuel with Solid Biofuel, and in the late game you can even use Turbofuel which has unparalleled acceleration.
** Added functionality to change the preferred fuel of equipped Jetpack in [[Inventory]] window
* [[Patch 0.7.0.6]]: Fixed an issue where icons would show up blank after Holstering equipment that uses fuel
* [[Patch 0.7.0.5]]: Fixed a crash for [[Multiplayer]] Clients and [[Dedicated Servers]] Clients when using the Jetpack
* [[Patch 0.4.0.11]]: No longer requires Computers for its unlock (replaced by Packaged Fuel), making it a bit easier to unlock in early Tier 6
* Unknown Update 4 patch: Changed recipe from 25 Cables to 5 Motors
* [[Patch 0.3]]: Now consumes Packaged Fuel instead of Fuel
* [[Patch 0.1.5]]: Changed crafting cost from 3 Circuit Board and 25 Plastic to 15 Circuit Board and 50 Plastic

== Early game development ==
Prior to Closed Alpha, a basic "Jetpack" or flying mode was first used which allowed flying without using any equipment like the Jetpack.
