I'll give it a shot. Won't record it, just for the hell of it - the supposedly "unbeatable" mission got my interest. It's Alien Base 2, right? I messed a bit with loadout, but only used what was already on the Skyranger (dropped some useless rifles in favour of OP shotguns). We'll see how it goes
EDIT: What a mission! In short, I failed. Got some turn 1-3 setbacks (Just 3 guys spawning on the second elevator - and thus getting wiped, Kjotleik first; Warboy mis-throwing a grenade and killing 2 guys), then it was a slow, slow grind, killed 23 enemies, it was going OK till like turn 16, when my numbers dwindled below 8 and I couldn't operate two squads to full capacity. The biggest problem was the lack of flares onboard, which meant a lot of cheap shots from the dark (I lost at least 6 people to that).
I cleared about half of the map. Secured extreme corners with my 2 thin 3-men squads, but had no one left to cover the middle (than unfortunate spawn of 3 men separated + warboy killing Niculinux and Riemaia). That wasn't the biggest problem - once I was down to 3, it's only a matter of a single mistake. Meridian, Lion and Max Damage fought well in the NE corner, with HC, shotgun and launcher. They died about turn 20, after Lion mishandled a security tower. Then Max died, but took assailant with him - had a primed HE charge. Meridian launchered another from point blank and was killed last, when trying to run. Lion avenged his death few turns later, when yet another Floater triggered his proxy trap.
About the same time the second group lost SupSuper to a Cyberdisc and was down to Warboy, Ivan and Maltloaf. They fought on for several turns more, before being blastered all at once.
Highlights included Ivan tanking a Cyberdisc salvo and Warboy dodging another from point-blank. But Ivan earlier face-tanked a Reaper attack
And of course a ton of good work killing aliens, but that's rarely remembered
About enemies, yeah, Cyberediscs have a ton of HP and furry friends are reeel fast; but handling both is a matter of a proper formation. Also the aliens all have insane Reactions, never once did my soldiers react, even with half their TUs. But that's just Hardmode lore you need to learn before adjusting tactics. Out of 14, 1 dead from reaper, 1 from cyberdisc, 2 from Warboy, 3 from BLaster, 6 shots from the dark and one from a Floater actually outplaying me.
About weapons, autocannons, that I didn't have, maybe? Tons of raw damage, but I didn't need that kind of firepower. The one HC I had was pretty solid, the shotguns were great and the main weapon I used were grenades - Alien and proxies (no instant grenade bullshit ofc). Rocket launchers were quite useful, especially dispatching furry friends and clearing rooms; the fact that they're too weak to one-shot Cyberdiscs limits their usefulness. Rifles were completely useless, but it is to be expected when fighting in close quarters; I could use powerful SMGs instead. Autocannons would also be great if they had buckshot shells.
Armor is a joke, but at least it doesn't incur much penalties, so I guess it's fine.
Big problem was severe lack of trained personnel. Except for Warboy and Meridian, most of these men shouldn't be sent into a combat zone, much less on such a tough mission. Suprisingly lack of medkits wasn't an issue (only 3 wounded: Warboy, Meridian and Ivan, and only Ivan from enemy fire).
Oh yeah and it was my first time ever playing Hardmode
