https://youtu.be/muEKfeP_XsgI read Icy's thread about almost getting it on 0.9.9.7 (and noticed later the pinned thread that he actually got it. Congratulations to Icy!). Anyway, I also went with light travel but I chose scout instead of marine. I went into the arena having picked up 3 berserk packs and 1 light-amp goggles, with 160% health and a full inventory.
In general, when an enemy is about to approach I'll drop an item because that takes half as much time as waiting in place, so when the enemy is in range it will have less progress toward its next turn (so I'm more likely to get a double turn).
1-1 is pretty simple, get the 2 medpacks and minimize incoming damage. Because I'm so fast, it's unlikely that the sergeants will get out of the base quickly enough to shoot me before I'm in position. I'm almost twice as fast as a sergeant (as a scout AoLT my actions take 0.77 seconds and a sergeant's take 1.43 seconds), so I can punch him once to see if he's "heavily wounded" and if not I wait a turn and then repeat.
1-2 isn't complicated either, just get as good a clear as you can and hope you get enough powerups.
For the arena, I used my berserk, overheal, and cacodemon attacks to destroy as many corpses as possible. Then after that I sat on top of a corpse near the edge of the map and waited a whole bunch for the enemies to approach one at a time. I had 2 combat knives so I should've been throwing one of them (especially since the combat knife has a very decent chance of 2-shotting demons) but I didn't. At that point it was just a matter of hoping my medpack supply would outlast their damage. On the third wave I got a large health globe. I was expecting the large health globe to give me the full duration of a berserk pack, but it only lasted 20 turns. I wasn't going to get great use out of it. I also made a mistake; I was camping a cacodemon corpse and when I found out my berserk was running out I should've gone back to camping it.
