Rule Your Thirst!

From Halopedia, the Halo wiki

Rule Your Thirst! is an achievement in Halo: The Master Chief Collection. It is unlocked by finding and destroying the BLAST soda can on Warlord in Halo 2: Anniversary multiplayer. The achievement is worth 5 Gamerscore and can be unlocked in both matchmaking and custom games, though the latter is much more advisable. It also unlocks the "Warlord" Multiplayer Emblem.

Location[edit]

On the top level at the yellow side of the map, there is a tree root which is growing down into the back right corner (when viewed from the center of the map). The can is sitting in a crack in the wall just behind the tree root.
