**Filling the Trophy Case Achievement**

Only 1% of players have this achievement. Not that difficult; You just have to remember some niche medals. **Focus on the Barrel Kill medal first, as barrels are scarce** Then Triple-Hit if you favor Remote Det for the RL. I played Lazarus labs b/c the map has lots of possessed/unwilling at the beginning and you can knock out harder medals this way.

I made adjustments to a post that was on trueachievements.com that was for Kadingir Sanctum. I put them in an order so less memory is required while getting achievement.

Starting loadout: Equipment Power rune for the Super-Kill medal. Whatever you want for everything else.
I switch to Blood Fueled, Armored Offensive, and Savagery, for movement and surviveability.

Arcade Mode
Level: Lazarus Labs
Difficulty: Don't be a noob and do it on Ultra-violence at least.
*You don't need to complete the level for the achievement to pop.

-Medals-

Barrel Kill:
Kill a demon by shooting a barrel or a mine. **Focus on this one first, as the barrels disappear later on.

Super Kill - 5+ demons in a short period of time. Use a grenade at the beginning when a bunch of Possessed/Unwilling are lumbering towards you.

Mid-Air Kill - Very easy to forget, and takes some planning/kiting. I used a Revenant. Save him for last durning a combat moment and wait for him to hover. Have Gauss Cannon or Triple Burst RL ready.
Sometimes, he won't go into hover mode, but he still jumps around a lot and then it's Gauss Cannon or bust.

Triple Hit:
I don't use that Shotgun mod for this, so I get this one out of the way early. RL triple bust works as well, I believe.

Stunned Kill:
Plasma weapon mod. If there are Pinkys in the map, almost a given.

Death From Above:
While an enemy is stunned, double jump above them and execute a glory kill.

Glory Kill:
Perform a glory kill while an enemy is stunned.

Head Shot:
The Chaingun, Heavy Assault Rifle, Combat Shotgun, Super Shotgun, Gauss Cannon, Pistol, Plasma Rifle and even the Rocket Launcher are capable of performing head shots.

Direct Hit Kill:
Kill a demon with a direct hit from the Rocket Launcher, or Explosive Shot from the Combat Shotgun.

Gold Relic:
Shooting the mines causes them to explode and launch a relic. The relic stays gold for a few seconds, so collect it before it changes color to get this medal.

Silver Relic:
Same as the Gold Relic medal, but wait for the relic to turn silver before collecting it.

Bronze Relic:
After the relic turns silver, wait a little longer for it to turn bronze and then collect it.

Extra Life:
Collecting Doomguy bobbleheads grants you extra lives. They have green auras and are found floating throughout the map.

Multi Kill - 3+ demons, short period of time. Frag grenade on possessed or unwilling.
Kill a cluster of lesser demons using the Super Shotgun, Gauss Cannon, a grenade or other explosives.
(Imps, Unwilling, etc.) *you'll probably get this automatically.

Good luck, let me know if I missed anything.
