I don't know how unbalanced the weapons in the dlc are. But I'm also not sure whether they'll even affect speedruns.
I knew about this and deleted them in advance. It should be mentioned in rules that custom levels also affect game and should be removed. Only in my opinion unsubscribe was enough. I have to check if checking cache will make a difference or not.
Apparently this action is being performed for a long time, after a few hours the message really updated.
I seem to be having trouble editing and deleting my posts. Despite fact that the site shows that these messages have been edited or deleted, in fact this does not happen and after refreshing the page, messages return to their original form as if nothing had happened. These changes do not occur for at least 20 minutes. But I noticed that if you add a new message, edits will be made.
Sorry for translated English.
It can greatly reduce scale of the screen in the game, and since scope of enemies gaze depends on the scale, you can literally finish the game without using weapons, using only fists. I personally checked it and you can do it too by changing this setting to +2.
In my opinion, setting Zoom level offset breaks the game a lot and makes speedrun very simple.
I suggest to create a separate category with this setting along with custom difficulty and mutators, and ban Zoom level offset on the main category. Or just ban this setting if you want.
(I'm writing because worried that my WR will be broken with this rubbish).
