I'm curious since I managed to just obtain all five, but Phantom hasn't loaded yet. (By Golden Medals, I mean these.) Mark of the Unbroken- 15 or more kills and a deathless Crucible match. No Mercy- Invoke the Mercy Rule. (Basically slaughter your opponents in Crucible.) Phantom- Defeat seven opposing Guardians without taking any damage. Bulletproof- Win a Trials of Osiris/Elimination match without anyone on your team dying. Sum of All Tears- Win a Rumble match with a score greater than the sum of your opponents. Seventh Column- Rapidly kill seven Guardians. We Ran Out of Medals- 25 kills in one life. UPDATE: Fixed Phantom, added Seventh Column and changed title. Added We've Run Out of Medals. UPDATE 2: I managed to get We Ran Out of Medals on my Hunter! Took a lot of map awareness, with the spawns in Mayhem.
