Part of my XCOM: Defenders of the Earth series!
Sent my four colonels - Panicman, Hitler, Sledge, and Gravedigger along with my most lethal soldier - Major Bald Witch and Major Bondi Vet who had proved his worth in keeping people alive in previous missions to assault the alien temple ship. Upon arrival the ethereal boss began narrating the entire alien's plot and motives. Something to do with ascension. I didn't really care. The squad kept in tight formation right down the center passage of the ship, eliminating pretty much every type of alien encountered thus far. Near the end, having used up most of the med kits they came to a large chamber with a pair of sectopods. Even Bondi Vet couldn't save Col. Sledge from the dual searing beams - one cutting through the colonel's face, the other through his crotch.
Hitler's new found rift ability ended that threat quickly, and after a few more mutons the team advanced across a thin passage to the final chamber where they encountered the ethereal boss, who prompty summoned two elite guards and two other ethereals. In addition he put up some sort of force field, preventing Gravedigger and Bald Witch from entering the chamber!? Panicman ran up the flank and he and Bondi Vet opened up fire on the ethereals, but all their shots were reflected! Gravedigger landed a critical shot on the boss thing with his rifle but it survived, while Bald Witch took out one of the mutons (her only target) with one shot. Hitler mind-controlled the remaining elite for a second - just as he did one of the ethereals destroyed the poor creature with an energy blast.
The aliens then went on the offensive, mind-controlling both Hitler and Bondi Vet. The Australian, unable to resist the powerful psionic energy screamed in pain as he was molecularized into purple nothingness by the boss ethereal. Panicman, the last one active in the room, managed to flank and wound another of the ethereals before it disintegrated him too. Gravedigger was on overwatch since he had no more targets until a shape suddenly moved into view - he fired instinctively but the shot only grazed his target - HITLER! The two psionics stared down each other just a moment before Hitler dismembered Gravedigger with his heavy plasma.
In a blink, Hitler had regained control of his mind - and he took cover on the highest platform to regroup. Meanwhile Bald Witch managed to get a shot off on the ethereal boss, but still not enough to down him. It responded by mind-fucking her to death, exploding her head in an orgasm of blood and brains (aliens are sick). It didn't notice Hitler in the gangway above him though, and in a last ditch attack the german tossed two grenades down killing the alien boss which somehow killed the remaining aliens as well! Alas, this also began killing the temple ship itself as it began implode into a black hole. In order to save the rest of the world, Hitler heroically looked at the door and yelled "go" at his dead allies then raised the vessel into space and caused it to self destruct, killing himself in the process.
He saved your life.
Technically that was a team wipe but mission complete! :P
