What's your most "XCOM" moment so far?

Had a squaddie sniper get killed behind full cover by a crit from a disoriented sectoid, squaddie specialist nearby panics and kills the sectoid with a crit shot.

Five-man team perched on roof of building.

Enemy triggers Sergeant Dumbass' overwatch.

Sergeant Dumbass shoots the floor out from under Sergeant Luckless, dropping him through the floor to his death.

Sergeant Chicken and Sergeant Screwup panic and run into exposed positions, where they are killed by enemy fire that results in an explosion... and a fire next to Sergeant Flammable.

Sergeant Flammable catches on fire. Sergeant Flammable panics. Sergeant Flammable is shot dead.

Sgt. Dumbass, who caused the whole problem to begin with, safely extracts.

My solider missed a 99% shot on a MEC, which then promptly grenaded the area, instantly killing 4 soldiers

Attempting the achievement to complete by July 1st 2035 on C/I. During a capture mission i sent a squadie ranger off through acid to skulljack an officer. With no training he pulls off a successful mind hack. panics, runs back through the acid and shoots the VIP dead, without any concern for the Intel. I looked back and the officer is crumpled on the floor with 4 health and no codex to be seen. It takes two other soldiers to finish off the dying officer. Meanwhile Tygan is getting all excited about killing something that wasn't even there.

First my lead Ranger misses a 90% shot, bevor my grenadier crit hit a 30% and saves the day.

Literally just happened, and I have footage of it. It's rendering right now but basically my squad goes from "everything is ok" to "one of my guys is bleeding out, 2 are panicked, and 1 is wounded"... and then my heavy hits a 5% repeater shot on a freaking sectapod to drop it and turn the entire mission around.

"I'm gonna put these three guys behind cover on this cop car before breaking concealment to shoot this Muton. What could go wrong?" The Muton lived, my squad didn't. In their memory, I no longer use cars as cover.

I missed a 99% chance when the enemy was directly in front of me with a pistol. I was real mad.

Legendary Ironman,

Mission going perfectly, only a trooper and a sectoid left, everyone in full cover, flashbang both of them, disoriented sectoid crits soldier in full cover with his plasma pistol.

Edit:Grammar

Edit:Soldier that was critted was in full health

Whole level cleared except one chryssalid on a retaliation mission. Three soldiers placed on a 2nd floor balcony on overwatch + 1 ranger still in concealment + overwatch.
Lid unburrows, runs over, leaps onto 2nd floor and goes direct for sniper
miss
miss
miss
just as it's rearing back to strike the sniper, the ranger activates and shotgun crits it dead, knocking it over the retaining wall . . .
. . . and it all happens in slow-mo.
The Wachowski brothers could not have directed it better.

I haven't played XCOM2 in a week because my best soldier, corporal grenadier with blast padding, got one shot via critical behind full cover with the height advantage by muton. The rest of the mission went poorly, lost more guys on the following mission, I gave up on that campaign.

Had a full health colonel punched by an andromedon mech. Panicked. Ran through the acid trail, into a fire. Hunkered down. Burnt to death with the medic sitting across the road and the last enemy of the mission on <5hp.

Probably having my Colonal ranger crit by a Gatekeeper while Gremlined in full cover, dropping her to bleeding out, causing my Squaddie "Medic" to panic and sprint in the opposite direction.

It was only due to my Psi trooper's anti-panic field and Inspire that he got back in time to stabilize her.

On the first mission of the game, one of my soldiers modeled after a friend of mine, on his first move, alerted a civilian and broke our concealment.

He then got shot to death by ADVENT.

Not a scary moment, but quite the opposite:

Started up XCOM 2, got to the first mission past the tutorial. Nobody got hurt in the tutorial. This mission I got my first Purple Heart.

One of them (a character from the dev list with a "Twitchy" personality") panicked upon being injured by an ADVENT goon's potshot, and rushed behind a nearby tree flanking the trooper. He then shot the goon dead and earned a promotion.

He was assigned to Specialist duty at the end of the mission. I made him a Medic for added irony.

First long war campaign was still born after I had my A-team baleeted by a PANICROKKIT into a truck that the majority of the A-Team was taking cover.

The two rooks on the team were shot to death in classic 'We-Don't-Miss-toids.'

Move a soldier to cover on a truck, activates 2 pods. Serial Ranger manages to take out almost an entire pod of vipers, someone else mops up. Handle most of the second pod of advent, leaving some with no cover or poor shots. Their turn, Lancer runs to the truck guy and misses (or doesn't, but he doesn't stun him). Truck guy gets hit by some other shots, is at one. My turn, low health Ranger runs over to Lancer, crits him down to 1hp. Truck guy misses his point blank shot. Their turn, a sectoid panics a third troop, who runs behind bad cover and grenades the group consisting of my gunner, my serial Ranger, and a 1 health Lancer, killing them all.

This was shortly after losing my best specialist because I went too aggressive for civilians (retaliation mission).

On EU, my first play ever, after already being told by my friends to not get attached to my soldiers. First time seeing a chryssalid, shooting him in the face with 90%+ chance, miss. Lost my highest ranked soldier. Next turn he resurrects and kills my medic. Felt like XCOM punched me in the face.

Long War, beginning of lategame. Roster is already low and aliens are fielding Ethereals.

Missed two 84% chance shots, a 94%, and a 99% chance shot in on turn. Okay. We can deal. It was a gunner who missed one 84 and the 94, and a scout who missed the other 84.

Two ethereals appear out of the fog and then mind control the scout and gunner. Retreat everyone to the bottom of the subway, leaving my high health/defense assault towards the front because the gunner/scout will reach us and shoot with one turn remaining on mind control.

They land two sub 20% shots in a row through heavy cover, critically wounding him.

Alternatively, Long War rocket scatter. "Only, one tile, how far off can that be?" Rocketeer hefts launcher onto shoulder, aiming it about 70 degrees off-target, directly at my engineer and assault taking cover behind a wall. Oh. Okay.

This one was pretty bad too, but the guy in the picture ended up as the only survivor of the seven man team involved. He went on to become one of my best soldiers in that campaign. So I guess I kind of beat the odds here?

In LW, I was doing the terror mission with lots and lots of zombies. I had a newly promoted Lieutenant for whom I had a high career in mind, but he seemed to be having an off day. He missed several 80%+ shots in a row in the beginning, which was a bad omen. The going was slow but I managed to wipe out all contacts, until one lone chryssalid remained somewhere out of sight, but with only a few hp left. My lieutenant was specced for overwatch, so I hit Y and leaned back. The 'lid came out, the 95% overwatch triggered and... missed. The beast killed my lieutenant outright. I had to actually shoot the beast on the next turn and then wait for my lieutenant to reanimate as a zombie before I could kill him :(
