Me and the Boi's just finished the EE. Would've been 1st but died on a first run.

Steps.

1. Turn on Power.

2. Locate Dynamite and blow the safe under the counter in the Garage, then collect the key inside.

3. Use the key to open the crate in power and get the free WunderWaffe.

4. Use the WunderWaffe to shoot three glowing orbs around the outside of the map.

These orbs are easy to see but only appear after turning on power.

Orb 1 is above a telegraph pole behind. Pack a Punch.

Orb 2 is by the 115 Rock.

Orb 3 is visable from Double Tap, it's behind a tent.

5. After shooting the Orbs they'll converge by Jug. Knife this Orb, after a round it'll stop glowing and you can pick up the summoning key.

6. Place the summoning key on the stove in the diner. This will trigger a lock down. Survive the lock down.

7. After the lock down kill lighting jacks near the little generators. 1 is near Jug, another near the tent. The last is next to Double Tap.

8. After the gens are charged you can pick up the summoning key and run it around the map, recharging it at blue barrels similar to the magma-gat upgrade. The trail of barrels will lead you to Pack a Punch.

9. Place the key in the pack a punch. This turns it into a soul box. Fill it with souls until it's done. This will be indicated by the new blue radius you must stay in. Leaving this radius will damage you.

10. This last step is a rehash of the last Tag Der Toten step. Escort the key, stopping to fill it with souls so often until back at pack a punch. the Radius will shrink at pack so watch out.

After it's made it back to pack, and finished being filled. The Game will go back to normal.

Pressing F on the key will end the game.
