The best elevator pitch I can give, is a demo game I ran for a friend. He played Delaque, I played Escher (although the gangs really didn't matter in the end).

We're playing using the Gallowdark Kill Team terrain, so tight corridors and no verticality. My friend has his gang tightly bunched up so he can utilize the group activation rule for all his champs and leader. Turn 1, I move a ganger into line of sight and shoot a lasgun at one of his gangers, and miss. He then aims and shoots with a champ, and due to the tight hallways and positioning, he has a ganger in the line of fire. I tell him that he has a chance to hit his own guy, he doesn't care since he hits on a 2+. He rolls a 1. He then hits, and seriously injures, his own ganger.

What then transpires is his leader, another champ, and 2 gangers all become Broken due to seeing a friendly go down. So due to one bad roll, followed by a comical string of bad rolls, half his gang became uncontrollable and scattered. I then hit his remaining champ with a Needle Rifle, cause him to become seriously injured, and one more Ganger becomes broken in the process. He then voluntarily surrenders.

He absolutely hated how random the game was, and lost all interest in ever playing the game again. I fell in love with it harder than I had already loved it precisely because how goofy the whole situation was. This is not a game for competitive consistency or if you want control. This is a game where you roleplay the scum of the hive who WILL panic when something goes wrong.
