Pack-a-Punch (Ubersprengen)

1. Behind the Windmill, there will be a battery with a green light on top. Kill Zombies next to it to power it. Once it's filled, it'll stop taking energy from Zombies, and the green light will go out.
2. On Wave 5, there will be another battery in the Wine Cellar of the intact house. Once it's filled, it'll stop taking in energy from Zombies.
3. On Wave 10, there will be another battery across from the Lee Enfield wallbuy outside the bombed house.
4. Once all three batteries are filled, Pack-A-Punch will activate in the Windmill.

Pack-a-Punch Upgrade

Allows you to upgrade the Tesla Gun, Ripsaw, and Melee Weapons (into the Shadowed Throne variants).

1. Obtain a scoped weapon. I recommend using the M1 Garand with a 4X scope since it has a wallbuy near Spawn.
2. On the bridge behind the Windmill, there will be a rubber duck sitting on the far wall. Shoot the duck to activate the Shooting Galley minigame.
3. Ducks will rise from behind the wall. You must shoot these ducks before they go back down. There will be 16 ducks for you to shoot. If done correctly, an animal in a dress holding balloons will rise up on the left side of the bridge.
• If you fail, you can retry on the next round.
4. On the ground behind you, there will be a fuse that you can pick up. The fuse will be automatically inserted into the Pack-a-Punch machine.

The Sword of Barbarossa

1. Complete the Main Quest of The Tortured Path at any time at least once.
2. Around the map, there are seven rune stone (like the ones from Map 3's main quest) that you must give 1750 jolts each (12250 jolts total). If done correctly, the stone will glow purple. Rune locations:
• Inside the wine rack, left of Schnellblitz (Speed Cola)
• In some grass, left of the dead cow
• In a pile of rubble, right of the blue truck
• On the ground by some barrels, left of the outside stairs to the Wine Cellar
• In a box right of the truck with the paintings in front of the Windmill
• In a bucket right of the Windmill gears
• In rubble in front of the Armour stand in the broken house
3. Stand in the glowing ring between the two trucks in front of the Windmill and allow a Zombie down you. You'll be instantly revived with the Sword (you'll keep all perks, except Quick Revive on solo).
