From Halopedia, the Halo wiki
Breaking Quarantine
Breaking Quarantine is an achievement in Halo: Combat Evolved Anniversary that is awarded for escaping the Flood containment facility on the level 343 Guilty Spark in at most 21 minutes. It is worth 25 Gamerscore points.[1]
It is represented by a white outline of an analog clock with the number "21" beside it on top of a green octagon.
Trivia
- The name of the achievement may be a reference to the story Breaking Quarantine from the Halo Graphic Novel.
- The fact that the player must escape the facility within twenty-one minutes is a reference to the number seven, as 21÷3=7.
