Someone told me that the "Endless" trial actually does have an end on level 666, so I decided to see for myself, and confirmed that to be true. :) (With 100% kills on Inferno difficulty!) :D Endless Diamond badge too! WOO! :D
I've been working on this particular run since... Mid-March, I think? It took just over four months from beginning to end, playing a few levels at a time each day. I did it with a Survivor build, which wouldn't have been my first choice, but it's the first one that took off after a whole bunch of failed attempts with other classes and builds. (Most of which didn't get further than level 2)
I was helped from the beginning by Inferno difficulty randomly giving me the "lethal" buff, which gave me a 50% damage bonus for the entire game. (I haven't seen Kornel comment on that, but I suspect it might be unintended; I sure took advantage of it, though) :P
The other big help was the AV2 grenade launcher you see in slot 3 which kept me alive in the early game, since it has a "haze" modifier on it, which basically acted as unlimited smoke grenades, for keeping enemies from shooting at me, and was useful enough that I kept it around for the entire game.
My real workhorse weapon, though, was that "Git Gud" rifle (okay, the AWP long rifle, if you prefer) :P which I found on level 20 and gets a bonus for each kill, so in a game with as long a timeline as this one, it got up to almost 30,000% crit bonus, and I spent a majority of the game being able to one-shot anything, including charging archmedusae.
I also had a super shotgun with second chambre as backup, which was pretty nice. Once I got all the damage bonuses from low health, (including a damage bonus from the Kerberos' Heart relic) very little could survive two shots from it, so it was good for getting enemies that were around corners or hiding in smoke or otherwise couldn't be hit reliably with the GG rifle. :)
I also streamed myself live playing the last six levels, as you can see
here. :)
I've noted before that you have to get really good at killing medusae in this challenge, as evidenced by the fact that it was the number one most common enemy. This frequently meant I had to tank at least one hit from each of them, so I could do a wait action to guarantee a hit from the GG rifle, but it was very doable. Other things I noticed: I found 8 Mk3 manufacturing stations in the whole game, 7 of which were before level 364, and the last being on level 660. Also, I found 6 uniques in the whole run, all of which were after level 400. (Gives some interesting insight into RNG distribution)
I'm sure there's plenty more to say about this run, but I can't think of it right now, so I'll just say... yay! I've finally finished this thing! :D
