Whenever I’ve played Downfall III just assumed the deadly revenant was only wearing red pants. According to John Romero himself (in a very serious, not at all joking tweet) we now know these pants are made of meat. Or as Romero calls them, flants.
The Revenant of Doom II is an annoying bastard who can quickly kill the Doomguy with his homing missiles. In the original game, it also wore bright red pants and some soccer fields with rocket launchers taped to their shoulders. As far as I know, these pads are not made from meat. But the pants? These pants are real meat. I would take on human flesh, but who knows? In fact, John Romero probably knows.
If you want to learn more about the Revenant and its powerful missiles, this video by Downfall Expert Decino is worth a watch. I also took the time last year Rank all Downfall Demons, including our flants worn by mate The Revenant. (Spoiler: He did it pretty well!)
You learn something new every day.
