update: I managed to get down to irene and the policemen left. Maybe it's actually possible with some luck. I'm not sure if I can win yet...

Thanks I'm gonna take a look in a bit. Good tip on the suppressors having cover mastery, I had no idea.

Ok nevermind I won
this thread did not age well

the ice tima was mvp with the skill that turns him into cover with 100% block

I succeeded thanks to Giselle/Heixing synergy as sniper and ranger. Both can fire support each other (+ each suppressor) with Breakthrough equipped while Heixing can spawn poisonous clouds on kill, dealing nice dot damage. You can end up with 10 fire support between turns.

Oh I see, I'm not sure if I even have the fire support mastery. i set my heixing to sweeper and left him at that which isn't very good in this mission it seems.

ah yeah sweeper is a more aggressive class imo, about rushing in with a buffed sweeping fire, where ranger leans way more on a defensive style, staying in cover with a buffed overwatch. There's a lvl 42 blue mission with snipers that drop the fire support mastery, otherwise i'm pretty sure Heixing can get his ranger sets at that point.

You get access to fire support as soon as you recruit Giselle, though you may have to research it.

Sweeper Heixing is very good on that mission if you have Re-Mop Up from Felix. He can spam several Sweeping Fires per turn, which makes short work of the VHPD units and puts the hurt on your party.

Look, I've beat the albus vs entire team one on my first try because it was somewhat doable with the main objective being to destroy the beacons, plus albus has insane block and damage output which means he can handle himself well. And the objectives were just low hp beacons you could kill easily if undefended.

However here you control a sniper and one other ally, with a bunch of pitiful suppressors, vs the whole team plus a platoon of tanky police units, and the main objective is none other than knocking everyone down. I've tried it 3 times using bots and animals as tanks but the enemy team's damage output is just too much and after 3 turns you just get swarmed. I've also tried using heixing but his damage output is not high enough to hold back the enemies, plus he also has trouble with block. I don't think it's feasilbe for a sniper to kill 3 tanks (albus, irene and leton) with high block in any efficient amount of time while they are running around punching everyone to death in one blow. Not to mention sion using chain lightning and knocking out multiple if he gets close.

Is it possible to do this without self sabotaging your own team?

Honestly, I put Giselle on Hunter and used the Queen Ice Negoori plus traps to disable/ kill most of the team. Personally Hexing and Ray were the 2 members that actually scared me during this mission because they're just insane at that point if built right. Luckily the AI isn't all that smart (or rather, if you give them a chance to take 'good shots' you can kinda force them into your traps).

Never tried it as a sniper though. I'm like 80% certain that Hunter is the better of the 2 classes and haven't really used her Sniper class since before they added synergy so...there might be significant changes that makes sniper better? Not sure tho

Yes heixing and ray were the biggest problem I had to deal with first. They had cover and pincer attack so I had to hit them outside their attack range or else Giselle would get shot. Luckily the AI is not great and in most games they'd just choose bad positioning which allowed me to snipe both of them.
I haven't tried hunter yet but sniper Giselle has so many mastery sets with so much synergy that I probably made a mistake in not equipping catharsis, since I had no room, so anytime I downed someone my only option was to use overwatch as I had no other attack to use with the free action from the sniper maatery. Probably would've been much easier with catharsis equipped.

But like I said before, the only reason I managed to win was because i could set up the ice tima with fortification and ice mane. That thing tanked for so many turns out in the open, and you can also heal it with the suppressors and Kylie. The tima was so foolproof you could probably win with Giselle on any build with it.
Also using the suppressors to throw the ice grenades before suppressing. That helped a lot as well so Giselle could take multiple turns while everyone was recovering.
