That ant that died... just seems like one of those ants that gets infected with a parasite that forces it to reach high ground, so that the parasite can transmit and reproduce itself on whatever other being that eats the ant that is in plain view... another zombie game? *does some searching* Oh fuck, it just might be. *looks closely at the video in the end* There's something slowly growing out of the ants head... Hahahahahahahah, another zombie game. I was wrong about it being a parasite, but nonetheless it's what I was thinking.
