Blood Gulch is the set for the machinima Red vs Blue. Duh. Who the hell doesn't know that? It is also one of the most violent battlefields in Halo 1. Casualties were 954,666,451,971,133,744,234,117 Spartans and very few Covenant. a similar place in Halo 2 was made by the grunt slaves (see bottom paragraph for more info)Squads and squads and squads of Elites were sent to Halo 2 Multiplayer to fight the Spartans without the help of Grunts or Hunters. It was such a massive failure, that the Covenant didn't want to construct another Blood-Gulch-looking place in Halo 3.This battlefield has been honored for its landscape, weapons, and bloodshed that it was named "Blood Gulch". This was usually the place that the Commies sent their POW Spartans so they can entertain the covenant by fighting meaningless battles. Noobs are common here, but they usually leave because people are too hostile and the climate. The climate in Blood Gulch is extreme that if you are stuck few yards in front of your base without a medic or a person wiling to take you in to the base, you are going to go through internal combustion soon.
Blood Gulch was remade as Coagulation in Halo 2, which caused multiple players to feel retarded when they couldn't figure out what the hell "coagulation" meant. Fortunately, they read archeologists discovered ancient tomes known as "dictionaries", which could define any word on demand, with the exception of "noob" and "pwn". After, the players found out what coagulation meant, they sighted in relief, and as a result, four-thousand and one fanboys learned how to read. Who says video games don't help you learn?
Blood Gulch is actually quite a popular area (if you didn't know that you're a Noobish Brute that huffs paint) for Cunts to watch demons battle. The grunts were actually concocting a special mixture of explosive gruntiness and SWAG inside of a cavern that is part of blood gulch, and they were secretly watching over it. The mixture can be found inside of dispensers with a shark's head attached incase you were wondering. Soon the Prophet of Fecal Matter and his honor guard of Brelites (brute/elite hybrids) discovered this and sold the grunts into slavery, ordering them to make a new arena. Little did they know they just gave Blood Gulch a graphics change, renamed it "Coagulation" and the Prophet of Fecal Matter bought it, only this time they added Elites to the mix because you are what you eat. I think.
