Hi I am just wondering if you need to beat both of the planets or just 1.

So far the speedruns have only been for Serpulo. Also people don't seem to be marking them as default vs. any loadout properly, all the 100% runs have been any loadout (meaning you launch to the next map with custom resources you select rather than going with the default). There's also a "no / yes" toggle to filter between runs and I'm not sure what that's for.

What about doing all the mini sectors like 37?

For a 100% do we also have fill every core? The rules should be more clear on what is needed.
