From this point officially, CoD 1 and UO runs will be splitted in NG and NG+. NG means that no fadeskipping at all is allowed, NG+ category allows it. Fadeskipping is a strat that involves loading a prepared-before-run save using loadgame_restart command or Restart Level button in the game menu. This allows to manipulate NPCs RNG and starting weapons. Fadeskips stay as a very controversial strat, decision might not be final, who knows?
UPD: as of 26/12/2021 NG and NG+ are made from sub-category into a variable as a compromise decision and keeping the board's integrity
Yes, not taking damage. I've tried for like 3 hours, and i've successfully done the first four level in glitchless + no oob + veteran + no hit. but the fith level seems really harder. I think the game can be done in no hit, but obviously, that won't be a run that will be done in a week. I'll soon post a record on veteran no oob, then after this i'll try the no hit run.
Of course by no hit I mean, if you take a hit, you restart the game from the beginng :)
Good luck :)
No hits are more of challenge runs and arent really accepted on leaderboards anywhere, (see dark souls no hit/ 1 shot bosses as examples.) So if someone were to accomplish this it wouldn't be added onto the boards, just a flex they can post and people can see.
