Side Quests:

Shoot 4 cowboy-like targets around the map for a free perk.
1. On the windmill to the left of spawn
2. On the water tower, adjacent to quick revive
3. On top of the mansion
4. Left of the entrance to PAP

Turn 4 levers to "on" in the maze in a specific order for a free Ray Gun MK2.
Turn each one to see a flicker of electricity to know it was the right one in that order.
The locations from the entrance of the maze:
1. The far right side of the maze
2. Behind the fountain
3. The far left side of the maze
4. As soon as you enter the maze, on your left.
(This was the correct order for my match)

Golden Shovel:
Find a shovel and keep digging up dig spots until you hear a noise and your shovel icon will turn gold. This will give you better luck and loot when digging from then on.

Music Easter Egg:
There are 3 miniature statues of Arthur/Leroy from Buried.
1. The left building after spawn, upstairs on the desk
2. Upstairs of the mansion, from the entrance, in the right side on a dresser
3. On a coffee table, in the hallway left of the power switch

Pack a Punch:
1. turn on power
2. activate the Der Eisendrache portraits around the mansion in the correct order (king, knight on horse, the great war, the knight's death)
3. collect the key from the upstairs right side room on the dresser (from spawn side)
4. use the key to open the gate to PAP behind the maze

Text Main Easter Egg Guide:
1. Open PAP
2. Dig up 3 TNT drops from dig spots around the map (golden shovel needed to do so)
3. Place the TNT on the fountain in the maze to spawn in an orb to escort
4. After escorting, use zombie blood drops to grenade 3 floating lanterns around the map.
They can be found just outside the front gate of the mansion, at the main staircase
inside the mansion, and behind the mansion in front of Juggernog. Grenade each of
these in zombie blood to pick them up after they fall.
5. Place the lanterns on the stair corners at PAP then shoot the glowing one to begin a
time trial where you must keep shooting the subsequent glowing lantern to complete it.
6. Once completed, go to spawn where you can now collect the wonder weapon at the
gravestones. Main Quest complete.
