Free-For-All
From Halopedia, the Halo wiki
Template:Ratings Free-For-All, colloquially termed "FFA", is the exact opposite of Team-based gametypes.
Overview
In Free-For-All, every player in the match is an enemy. Players no longer work in teams and must be dependant enough to survive and eliminate other players. Performing suicide will extend the respawn time and one point will be deducted from the suicider's overall score.
Free-For-All is available for most gametypes, such as King of The Hill, Oddball, Headhunter and Slayer.
