Repair Tool (Subnautica)

The Repair Tool is a tool used to repair damage on vehicles, Seabases (Subnautica), Lifepod 5's Radio and the secondary systems, damaged doors in the Aurora and its drive core. It is powered with a Battery (Subnautica).

Uses
The Repair Tool is first used to repair the damaged panel to the left of the Fabricator (Subnautica) in Lifepod 5 and the Lifepod's Radio, which allows messages to be received (though not sent, as the protagonist is silent).

Afterwards, early on in the game while exploring Wrecks, there can sometimes be a damaged control panel usually identical to the one in Lifepod 5 for doors, which then allows for access or easier access to an interior. Later on, its main role is to replenish the health of the Seamoth, Prawn Suit (Subnautica), and Cyclops, and to fix holes in the hull of the Cyclops and most Seabase modules. It can also repair breaches that appear in the Aurora's generator room, thus causing the radiation to begin to dissipate.

As it comes with its own battery when fabricated, this can be an alternate way to make new batteries if Acid Mushrooms and Copper Ore (Subnautica) are not readily available.

If a Bleeder latches onto the player's arm, the player can use the Repair Tool to hit the Bleeder.

Trivia

 * The idea for the Repair Tool may be taken from Natural Selection 2, where the Welder is used to repair various machinery, much like this one.
 * The original name for the Repair Tool was the Welder.
 * The Repair Tool doesn't require a battery in its recipe, yet spawns with one inside of it, creating batteries without any copper.
 * Unused animations from Trello suggests that the Repair Tool would have operated using consumable canisters of welding material, rather than batteries.
 * In former versions of the game, a Repair Tool and a Diamond was used to create the Laser Cutter.
