Can someone please explain to me how the grunts managed to unionize, start basic scientific reserch, start modifying there specicies, then eventually splicing a grunt embryo with some f*cking reptilian crap to make a new hybrid species that woud actually die because everyone knows that the grunts methane tanks are super-cooled, which would super-cool the reptiles blood as it passes through the body? Or am i expected to believe they evovled in 4ish years? COMe ON 343 GET YOUR HEAD IN THE GAME! litterally!!!
