I have done a race with zgl and mrsantos24

And any run in the new game category does not use any unlock ables like infinite ammo and the circular saw

Races have been done yeah, there is a specific chat room on the RE discord for races(link to the discord is on the forum I believe the thread is called "Is there a discord?" or something along those lines).

For the NG+ runs, technically every run is NG runs, but you pick up unlockables like infinite ammo, albert and circular saw. Those unlockables are also the only reason to run NG+ category.

NG easy on the other hand don't use any unlockables. (same for NG Madhouse)

Hope this help.
