I remember back in the times I read about Compet-n modes the first time, I was thrilled, trying to do pacifist, tyson, etc. I do distinctively remember of trying another mode (but now I realize in the doom wiki maybe it doesn't exist and I made it up) of playing regularly but trying not to be hit. If I was hit, I'd start the level again. Later on, when I tried a new map, I would always have this habit. In the beginning of the map I play very carefully and just notice when is the first time I unfortunately get hit (it was especially interesting with hitscanners and I would strafe back and forth from behind walls, peeping fast and back till I was sure everything was clear) so I would notice that in this level it took me 10 secs, in another level I survived more than a minute, etc.
I want to try that again, or variations of it, so I am wondering if there is a mod (or a simple hack) to:
1) Start Doom with health 1% (maybe a dehacked patch? Never used this)
2) More important, is there a tool that reads all maps in a WAD and removes or replaces every health/armor/powerup item?
3) The above is necessary for 1, but I am also thinking of another mode that could be interesting. Start normally with 100% health (or maybe give 200% health/armor start on level one) and see how far I can reach in the whole game/episode without dying, like a Doom marathon or something.
