UHEC

Most of the men had tried shooting at the Old Orange, but Olympe simply ignored them, or at most mocked them, challenging them to keep firing. Few of them took up that challenge.

I've operated with U-HECs six times, and each time, it's been fucking intense. Even if you're inoculated against the cognitos, it's fucking terrifying to see that huge thing smashing through small buildings and shrugging off small arms fire like rain.
