Gears of War 3 came out on Tuesday, and it’s a blast. A lot of the enjoyment has to do with the ridiculous weaponry, like chainsaw bayonets, guns that shoot living grenades and orbital laser cannons, and insane enemies, like the Locust Drones, Corpsers and the Lambent. Obviously, when you’re dealing with such fantastical elements there’s a (rather large) degree of implausibility, if not outright impossibility, you just have to accept, right? It seems that’s only partially true. According to this Gamepro article at least a few of those elements are somewhat plausible according to several PhDs. So, the chances of there being independently evolved Homo Sapien-esque organisms on another planet is greater than finding an underground Godzilla and raising him as a pet? Bummer.
