Big Game Hunter
From Halopedia, the Halo wiki
Big Game Hunter is a medal available in Halo: Reach multiplayer and Halo 5: Guardians Warzone. In Halo: Reach it is earned by getting the highest point kill of all players in a co-op session of campaign or Firefight. It is represented by a blue ribbon in Halo: Reach and a bear paw inside a blue square in Halo 5: Guardians. This medal appears only on Bungie.net's post-game carnage stats when earned in Halo: Reach.
On March 31, 2012 Bungie.net ceased updating Halo game stats and player records, transferring all record-keeping responsibilities to Halo Waypoint. As Halo: Reach's Big Game Hunter medal could only be viewed on the site, it is effectively no longer awarded.
