Jetpack

Dominate the verticality of the alien ocean with personal flight.

The Jetpack is a versatile personal propulsion system essential for survivors stranded on Planet 4546B. It allows the user to fly through air and swim with enhanced speed underwater, providing crucial vertical mobility that standard swimming cannot match. This piece of technology bridges the gap between surface exploration and deep-sea diving before larger vehicles are fully operational.

Lore & Background

The technology is distinct from the alien architecture found within the Precursor structures, remaining purely human engineering. Its design prioritizes portability and rapid deployment over raw durability, making it a disposable tool for many who venture too deep without backup power. Despite its limitations compared to the Seamoth or Prawn Suit, the Jetpack remains a symbol of human ingenuity in an environment that constantly seeks to pull explorers down.

In Their Own Story

The water grew cold as the survivor ascended through the kelp forest, the thrum of the jetpack vibrating against their spine. Above, the surface shimmered with false hope, but below, the shadow of a Reaper Leviathan stirred in the silt. With a flicker of blue light from the battery gauge, they surged upward, breaking the water's tension just as the trench darkened behind them. The silence of the air was a reward earned by speed.

Reader's Guide

To craft the Jetpack, players must visit a Fabricator and combine twenty units of Titanium with five Gold and ten Lithium. This recipe makes it an early-to-mid game priority, as Gold is often scarce in shallow waters. Once equipped, the device functions by consuming power from a standard or rechargeable Battery inserted into its slot.

In air, the Jetpack provides rapid vertical ascent and controlled descent, allowing access to high cliffs or wreckage without climbing. Underwater, it acts as a powerful thruster, significantly increasing swim speed and reducing oxygen consumption compared to treading water manually. This dual-environment utility makes it invaluable for traversing complex biomes like the Blood Kelp Trench or escaping sudden predator encounters.

Strategic users keep a full battery charge before diving into deep zones where Reapers may lurk, using the burst speed to create distance quickly. While it does not offer vehicle upgrades, swapping in Rechargeable Batteries extends operational time significantly between recharges at charging stations or via solar arrays.
