While your spacesuit and ship help you survive and navigate the galaxy of No Man’s Sky the multi-tool helps you mine materials and fight enemies. While collecting resources is generally a straightforward and conflict-free activity, there is a chance that planetary defenders, named Sentinels, will attack you for your transgressions.
Thankfully, the multi-tool can come with different weapons that uniquely deal damage. Since all the weapons in No Man’s Sky are pieces of tech, you can augment a single multi-tool with multiple forms of damage.
