There's nothing to really collect or do, it's a very linear game.

If I am correct, 100% Runs are runs that involve beating all the extra objectives, Any% is how fast you can beat the level no matter what objectives you do. In 100% you have to beat Main/Secondary/Overload if any of those are in the level.

Thanks!

Does that mean that technically if a run doesn't have any secondary objectives that the Any% run is also a 100% run?

I'd guess yes, it probably just goes under any% as to not clot up both categories, even though they are per definition in main only missions, the exact same.

I suppose, personally I'd submit it to both when applicable just for the sake of it

For future reference:

100% runs pertain to levels that are applicable to this. Any rundown expeditions that do not have optional objectives will be placed under Any%.

Please submit levels with only 1 objective under Any% categories.
