How to repair the Javelin in Revenge of the Savage Planet

To actually repair the Javelin, you'll need to 3D print new parts. Theblueprints for these parts are unlocked by finding and scanning threeother crashed Javelins scattered across the different planets:

• Xephyr (Antenna): Travel to the north-west part of the Xephyr map. You'll find the crashed Javelin surrounded by distinctive Coupon Crates. Scan the Javelin itself, then climb to the top of it and scan the Antenna.
• Zenithian Rift (RCS Thruster): Teleport to the Summit of Ruin on Zenithian Rift. From the teleporter, follow the north path down the icy slope. When the path splits, take the left fork. At the end of this path, you'll find the crashed Javelin.Alternatively, you can use the outer rails to navigate to it. Scan the RCS Thruster located at the back of the crashed ship.
• Quasadron IX (Radiator): On Quasadron IX, look for a distinctive Baobab Maw tree and a small inlet just south of the main teleporter. Head to Savannah Lake and dive into the main lake. Swim north and descend to the very bottom. You'll find the crashed Javelin submerged there. Scan the Radiator and then return to your base.

4. All Upgrades, Costs, and Achievements:

Once you've scanned the three crashed Javelins, new upgrades will becomeavailable in your base's 3D Printer, in addition to the two defaultupgrades. Here's a list of all the Javelin upgrades and their resourcecosts:

Before heading to the 3D Printer, make sure you've diligently stocked up onthe necessary materials by exploring and collecting resources across the planets. Once you have enough resources, fabricate all five upgrades.

Finally, interact with the Javelin at the crash site to install all the newly printed parts onto the ship. Once all the parts are installed, enter the ship.

This action will complete the Roundtrip 2.0 mission and unlock the "Hasta la Vista" achievement, signifying that you've successfully repaired the Javelin and(presumably) returned to Earth, albeit with a humorous twist ending.

Furthermore, if you have also completed the "Best Served Cold" questline before entering the repaired Javelin, you will unlock the "Revenge is Best Served via the Internet" achievement simultaneously, rewarding you for uncovering the corporate conspiracy against Martin Tweed.

Repairing the Javelin is a significant time investment and requires thoroughexploration and resource gathering, but it's a key step towardsexperiencing all the narrative layers and endings that Revenge of theSavage Planet has to offer. Good luck with the repairs!
