Ok, so I've completed this N! rocket challenge which arguably is the easiest one. The main obstacles I encountered were obviuos weakness against robots, since I ran master-less and a great scarcity of ammo. While playing on Hard you expect ammo to cause troubles around Io, and it was a hard-learned experience. I will never forget that time when i got to Summoner and had to try and tackle it with my bare hands since all rockets depleted.
N! is much uglier in that regard. Even on Europe I began noticing that often a rocket blast leaves a few HP on reavers which doubles the expenses of precious ammo. That's why I tuned my marine build to max early damage output and took twice Army Surplus in the latter stages to comfort my anxiety of running out of ammo. To take angry MF perk you have to invest one useless into SF, but it is worth it, since it is the only way from all three classes to increase the rocket damage output.
Two ironmans gave plus 40 hp, and I was eager to use every Heal Station to increase health by 5 more. Imagine my surprise when having loaded 3 multitools in another one I discovered that my HP stayed the same 160. Those kind of limits are not told to you, so it may be useful for you to keep that in mind.
This whole build was "bet on myself and don't rely on stuff" but finding an autoloader launcher in CalSec Central was a pleasant surpise. Sure it helped. Asterius breach is useless and annoying to clear on N!, so I won't visit that resort again. Almost died there.
So here I am.
