What are mods/mutators? And, what are the rules about different perk levels? Just interested in doing some runs and want to make sure I follow the rules correctly.

Well any perk level is fine but of coarse the higher the better., no mods or mutators (e.g trader time changer) basically it I think fairly straight forward.

Cool, thanks.

A mode that can be interesting not ?

• take 10 medallions as fast as possible

Medallions?

10 Items collection

I don't think we should even worry about collectibles since it has no real affect on the game and is not really important in the runs anyways it would just be a pointless category to have imo.

Okay ^^

If we want to try and have challenge run categories like no trader that could be something. ( no use of the trader whatsoever, pickups for ammo and weapons etc allowed. )

Yes its can be nice x)
