Do extra lives and other pickups that show up on a map, count towards 100%?

That hasn't been discussed yet. But I did write a potential ruleset for the category:

Play from fresh save file.

Time begins on game start. Time ends at Icon of Sin kill cutscene.

Beat the game while:

• Achieving full Combat, Challenge, and Exploration rating in each level.

• Acquiring every Weapon and Suit upgrade.

• Unlocking every section, and collecting every item in the Fortress of Doom.

You should have collected all:

• Weapons (including the Unmakyr)
• Weapon Mods and Mastery
• Runes
• Sentinel Crystals
• Sentinel Batteries
• Praetor Tokens
• Mastery Tokens
• Codicies (collected from map)
• Toys
• Music Records
• Cheat Codes

Again, that is a potential ruleset, but it's not written in stone.

Will there be more categories? Like 100% and Any% ? Or single stage run or something similar?

OCD category maybe as well?

In addition to above -

-Leave no enemies alive. -Collect everything that's marked on the map

There will be many categories to pick from! 100%, All Collectibles, Any%, to answer your question Lukol97 there will be IL (Individual Level) leaderboards. I'm positive some people will run Ultra Nightmare.
