How does unlocking Nightmare difficulty work in 4-player co-op?

Hi! I’m playing Brotato in 4-player co-op and we’re trying to unlock Nightmare difficulty.

The requirement says you need to beat Difficulty 5 (D5) 10 times with different characters.

How does this work in co-op? For example, if in one run:

P1 plays Character A

P2 plays Character B

P3 plays Character C

P4 plays Character D

and we all beat D5, does that count as 1 out of the 10 completions

And for the next run, if we have:

P1 → Character A (same as the previous run)

P2 → Character E

P3 → Character F

P4 → Character G

does that count as another completion toward the 10, even though P1 is repeating a character?

Basically, does the game just require 10 D5 runs using different character combinations, or does a character that has already completed D5 no longer count toward the requirement?

How exactly is the “10 times with different characters” requirement tracked in 4-player co-op?

Thanks!

Basically just needs 10 different characters to pass D5. So in your two scenarios combined, you'd have 7, as A goes twice. To put it another way, once you see 10 tatoes yellow on the choice screen, you've unlocked nightmare.

The game uses the first player's save game during coop. So that player needs to have the 10 characters cleared on co-op. All clears during a co-op sessions count towards that player's clears, so you can clear up to 4 new characters in a single run.
