Blood Gulch

Blood Gulch takes place in a box canyon that is enclosed on all sides by high natural walls. The canyon's interior is a "vast expanse of undulating landscape and scattered pieces of natural cover", with a base on each end for the Red and Blue teams.[2] The map is balanced but lopsided in terms of tactical advantage, with the Red team having access to a ridge, while the Blue team is located near a tunnel system in the canyon wall. Each base is conducive to traditional FPS gameplay, with "two entrances, an open ceiling, and sloping paths to the roof".[2] On top of each base, a teleporter can transport players (from either team) to the midst of the valley's no man's land, leaving them vulnerable to snipers. Warthog jeeps can easily traverse the landscape, making them ideal for escaping with the flag.[2] In the Halo 2 variant of the map, each base has a third, below ground level, in which a Banshee can be found.

Edge Magazine called the map a "showcase" for Halo's "wonderful ability to segue in and out of tense firefights and moments of ridiculous slapstick". The publication praised the map for its wide open design and combination of ground combat and third-person vehicles, which, while taken for granted in the modern day, was rare at the time of Halo's release and required "a different approach to map design".[2] Good Game called the map "Halo's most iconic" and said that "teamwork is at the core of the Gulch", while "the best way to experience the gulch has always been behind the wheel".[3] GameZone called the map "easily a standout of the franchise", citing how often it has been remade across games.[4] Phil Spencer, head of the Xbox brand, called Blood Gulch his favorite Halo map, citing its terrain, large amount of vehicle combat and the excitement of coordinating friends to capture the flag.[5]

Blood Gulch was recreated by a fan for the game Counter-Strike: Global Offensive, with Kotaku calling the map "very nicely done".[6]
