Pack-a-Punch (Ubersprengen)

1. Beside Speed Cola (Schnellblitz), on the left side of the map, 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 near Stamin-Up (Laufenblitz). Once it's filled, it'll stop taking in energy from Zombies.
3. On Wave 10, there will be another battery next to the Pack-a-Punch machine (right side of the map).
4. Once all three batteries are filled, Pack-A-Punch will activate.

Pack-a-Punch Upgrade

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

1. On the Rune Wall at the top of the map, shoot these runes in order (or use this image ).
2. A hole in the wall will open left of the Laufenblitz (Stamin-Up) machine, revealing a fuse for you to pick up.

The Sword of Barbarossa

1. Complete the Main Quest of The Tortured Path at any time at least once.
2. Drop 1750 jolts on each of the four Sacrifice Stones around the map. If done correctly, the stone take the Jolts drop. Stone locations:
• Spawn
• Left side of the map, up the stairs from the Laufenblitz (Stamin-Up) machine
• In the Rune Wall room at the top of the map
• Right side of the map, up the stairs from the Pack-a-Punch machine
3. Drop 1750 jolts in front of the three bowls in the Forge Room (where you placed the parts in the main quest). If done correctly, the jolts will disappear.
4. If done correctly, a glowing ring will appear around the Forge. Stand in the glowing ring and let a Zombie down you. You'll be instantly revived with the Sword (you'll keep all perks, except Quick Revive on solo).

Kontrollgranates (Turned Zombie Grenades)

1. Throw a Jack-In-The-Box at five metal Klaus symbols around the map:
• Up on a rock behind Lebenblitz (Quick Revive)
• On the back wall between barrels, behind Schnellblitz (Speed Cola)
• Above doorway left of Kugelblitz (Double Tap) between two pots
• Above M1 Garand Wallbuy behind vases (you can't see the symbol)
• On the scaffolding across from Faustblitz (Melee Perk)
2. When all five Klaus symbols are blown up, there will be an earthquake and a box will fall onto the stairs near Spawn with Kontrollgranates inside. This is the same box as the one in The Tortured Path Main Quest.
3. These grenades will create a gas that turns Zombies friendly. These Zombies will attack other Zombies.
