I play single-player on skill 3 without saving, other than the beginning of the level, and I have to say that this pack is killer. I've lost count on the number of tries I gave warpa to complete it, and then I gave up on warpb a few months ago. I recently tried the pack again, and started grueling through warpb.
I started recording demos of my attempts once I was able run through a half hour of gameplay without dying. And, today I finally passed it.
Unfortunately, you cannot record from a save file, so I didn't start with anything from the previous level.
Keep in mind that this isn't a speedrun, I kill everything I see. I managed some interesting manuevers, but I can't say that it is as entertaining as the latest speedruns I've seen... I reviewed the demo and found that I go back for armor three times, but in total, it's about three minutes of not-so-entertaining times.
