how do i heal my tadpole subnautica

You heal the Tadpole in Subnautica 2 by using the Repair Tool on the damaged vehicle. Current guides and recent community posts agree that the Repair Tool is the main way to restore Tadpole health, and you need to craft it before you can fix the vehicle.

How to do it

1. Unlock the Repair Tool blueprint by scanning the required fragments. One guide says you need three fragments.

2. Craft the Repair Tool at the Fabricator.

3. Equip the Repair Tool.

4. Approach the damaged Tadpole and use the repair action until the health is restored.

Extra notes

• Batteries do not heal the Tadpole; they only provide power.

• Damage can come from collisions, hostile creatures, or rough terrain, so repairing early is safer.

• A recent forum tip also mentions that some players restore full health by breaking the Tadpole down and reassembling it, but the Repair Tool is the standard method.

TL;DR

Get the Repair Tool, equip it, and repair the Tadpole directly.
