"The "4" in the name comes from there being 4 playable characters, you see. Which is a bit weird, since Back 4 Blood has 8 playable characters. Yeah, you can only have four playing at a time but if you're into number puns there's a lot you can do with 8. "Running L-8", "Zombies 8 My Face"? Oh wait, not zombies, "infected"! No wait, not "infected", "Ridden"! Ridden? That's a word that just reeks of "we had to come up with a legally distinct alternative," isn't it? No one in reality would call them "The Ridden". What, are we up against a resistance group founded by disgruntled domestic horses? I keep misreading it as "the Riddler" and wondering if civilization has finally been brought down by Batman's most confounding foe."
