Upgrades are a feature of the Barotrauma Campaign. At an Outpost, subs may have their hulls and systems upgraded in a variety of ways to improve durability and effectiveness. Repairing walls, items, and shuttles wholesale is also possible.

Outpost

These are purchased from the engineering crew chief at any station, who is usually in the station engineering section with the reactor and the oxygen generator, plus a fabricator can also spawn randomly in this area. They can be seen wearing the Crew Chief's Outfit and an unpowered Headset with the Upgrade symbol above them. They also possess a Wrench, a Screwdriver, a Diving Mask, a loaded Revolver and a Toolbox containing the same items as their sub selling partner.

The crew chief offers multiple upgrades per upgrade category to further improve them, but each additional upgrade in the same category also costs more than the one before. Thus, more money buys more and nicer things. Each sub may be upgraded independently of all the other subs, so how many different subs the player chooses to invest their hard-earned marks in is up to them. The pricing of their services is dependent on the RP of the current Outpost, specifically 1 RP is equivalent to 0.5% of the price. Therefore, maximum discount is 50% off at 100 RP, and at -80 RP they will charge 40% extra. Much like Store, the price gets higher beyond -80 RP as the entire Outpost hound for the crew's blood.

Upgrades

There are 13 parts of a standard sub, each with different types of Upgrades and each Upgrade has multiple levels. There is a total of 22 different Upgrades across all parts. Once the first level of an Upgrade is purchased, the second level will cost 16% more than the first. And the third level will cost 17% more than the second, then the fourth goes up 18% and so on. Some subs may lack upgradeable parts, commonly a Fabricator and a Deconstructor, meaning no Upgrades available for those parts. All Upgrades will be applied to the sub before departure.

The following list displays all Upgrades and their price at 0 RP.

Maintenance

Keeping the sub and its installations in good condition is crucial for the crew's survival when traversing the Europa's ocean. This can done manually by individuals skilled in those aspects. But if tedious business and effort in general isn't the player's style, they can always throw money in Maintenance and get things fixed up automatically instead. The same can't be said for the shuttle if the crew happen to lose it along the way since the only way to retrieve the lost shuttle is to replace it for a new one in Maintenance. The price of the services is affected by the RP in the Outpost the same way as in Upgrades and is shown below at 0 RP.

Service	Price
Repair All Walls	500 mk
Repair All Items	500 mk
Replace Lost Shuttles	1,000 mk
