All of you idiots.... Blood Gulch is the original Coagulation, Valhalla, Hemmorhage, Ragnarok. Blood Gulch is the ORIGINAL! Get it right man get it right.... (Yes im a halo nerd if you're wondering and love to tell people u have it wrong ) But seriously guys, how could you not have know this???
Don't compare Gulch to any of those, its never had a remake. Coagulation had a basement/second level and Hemmorhage... just no.
