Ah, yeah. I experienced my first full squad wipe ever in almost the same circumstance. I remember hopping into a fresh game with this mod pack I had never tried before. It was also Superhuman and I was creeping through a Mayan junglescape with my starting crew. As soon as I got off the Skyranger, I took heavy losses. Before the Final Mod Pack, I named my enemies Tangos, or Gellies, or Fat Charlie. Whimsical stuff that made me laugh. I took floaters more seriously after Gary Hardin, Hanni Fallis, and Jesper Falks were the only soldiers left. They blew out our brains as I marched through the jungle with only pistols and light rifles to bring to bear. It's funny how you forget how much you use every single soldier in your crew until you only have eight rookies to work with.
Oh, but the others weren't all dead before I got to the UFO. A quick handed soldier with a pistol and a slow, heavy hitter that expended four or five grenades were still there, and I prepped the breach. Unlike you, my breacher went down as soon as I stepped in. It was a poor decision jumping in like that. Gary went down, unconscious on a mission without medkits-the alien had shot him when I moved him in after the breacher. They got the grenade slugger the turn after-rat bastard of a floater just walked right out and shot her. I walked in with my three and covered a single door.
The following turn, I popped the door rather than wait for reactions to bail me out. Hanni went down hard. She hit her shot, but with a crappy pistol it wasn't enough. Private Jesper killed the alien bugger, and proceeded to draw reaction fire from another floater behind him. Incredibly enough, he survived, but took four fatal wounds in the process. Gary Hardin took his shot and missed. The bullets passed through the armpits and cape of that damned back floater.
Hardin ran for it. Jesper was shot behind him. To this day I still don't know if the floater that burst out and killed him was the same one that killed Jesper Falks.
