Got laser on 12nd floor ( and firestorm pack to it ), 1st nuclear BFG on 20th, first power mod on about 30+ and then 2nd BFG.
By this point there was no way to lose... need just do something really stupid to die.
That's a really nice stash early, not to mention Necroarmor (and Onyx pack if you got, say, phaseshift, although OAP red's just as good). Even without Ammochain, it's hard to see something losing with such a build.
Also for the first time I found Dragon Slayer... and couldn't pick it up to look more bad ass in the end:(
DS has specific requirements to pick it up, which will never be mentioned on this forum (as a matter of respect), but the hint I always give is to figure out where the weapon comes from: it's a pretty short hop from there.
There seriously need be badge for beating this mess without ammochain and lot more nightmare monsters even on easier difficulty.
With the current setup of badges, it's hard to say where that kind of badge should go. A100 by itself is considered Gold, and the next setup is N! A100. Frankly, I think N! A100 should be pushed to Diamond, given that the current Centurial Diamond is impossible in every sense but literal, with UV A100 (or some variant) as the Platinum.
MAc simplifies A100 considerably, that's a fact. On the other hand, I can't imagine winning N! without it: there are times when you need to use hundreds of cells without end. I've beaten HNTR A100 using neither MAc nor Intuition, and that was pretty hellish...I don't think I would have survived had I not found nuclear weapons near the end (admittedly I think I was aiming for YAAM, but still). If there was a more reliable supply of ammo, like some kind of guaranteed depot every five/ten floors or so, then I would be more inclined to attempt it on a harder difficulty. Frankly, surviving 100 levels WITHOUT worrying about ammo is a challenge unto itself.
With regards to N! A100, I think I put it best in my guide when I wrote "This is the kind of badge you only get when you're bored and have a ton of time on your hands." Although, Christmas is coming up, so...
