Red vs. Blue (achievement)
From Halopedia, the Halo wiki
Red vs. Blue is an achievement in Halo: The Master Chief Collection. This achievement is obtained by winning 10 matches on Bloodline on Halo 2: Anniversary multiplayer. The achievement is worth 10 Gamerscore, and unlocks the "Puma" Multiplayer Emblem. This achievement can be unlocked with both matchmaking and custom games.
Trivia[edit]
The achievement is, naturally, named for the Red vs. Blue webseries; the majority of the first five seasons, known as "The Blood Gulch Chronicles", take place in the classic box canyon. The Puma emblem that this achievement unlocks is a reference to the debate Grif, Simmons, and Sarge have on the name of the Warthog in Red vs. Blue Season 1, with Grif saying that it looks more like a "big cat" than a "pig", and suggests calling it a "Puma.".
