First up, the Fused Conductor. This one’s always somewhere in the Power Station. Most of the time, I spot it sitting on a barrel right next to the generator. Other times it’s perched on a control panel in that little office above the generator. It’s a chunky bit of kit with frayed wires hanging off, so it’s pretty hard to miss. Next, the Vacuum Tube Array. You’ll need to head down into the Research Labs for this. It’s a fragile-looking glass and copper piece, usually lying on one of the lab benches with all the odd beakers and monitors. I’ve also found it sitting on a metal shelf near the entrance to the containment wing. Just watch your back down there — zombies love to corner you in those tight hallways.
Finally, the Reinforced Housing. This one’s a breeze to find. It’s a big slab of metal, usually leaning against a wall in the Maintenance Tunnels. Sometimes it’s near a collapsed section, other times next to the water pumps. You’ll spot it straight away — it’s too big to miss. Once you’ve got all three parts, make your way to Ol’ Tessie’s console in the main chamber. You’ll see the build bench right next to that sparking mess on the wall. Hold your interact button and your character will piece it together. After a quick animation, the trap’s fixed and ready to go. Activation costs 1500 points, and when it fires, it sends out a huge electrical blast that fries anything dumb enough to walk into it.
But why stop there? If you want Tessie at her best, you’ve gotta upgrade her to Tessie’s Wrath. To do that, you’ll need to feed her a bunch of zombie souls. Lure a decent horde into the trap and trigger it — you’re aiming for roughly 20 to 25 kills with the trap itself. Once you’ve hit that number, her console will spit out a Pylon Key. Grab it and head to the Pack-a-Punch machine. Instead of upgrading your gun, interact with the side of the machine to slot in the key. For 5000 points, you’ll get a Charged Crystal in return. Take that crystal back to Tessie’s console, slot it in, and watch her power down for a moment before roaring back to life with a surge of blue energy.
Now you’ve got Tessie’s Wrath — bigger blast radius, faster cooldown, and she’ll even one-shot most special zombies for several rounds. It’s a serious game-changer, especially when the map gets hectic. Honestly, once you’ve done it a couple of times, it becomes second nature, and you’ll wonder how you ever managed without it. If you’re looking to push your game even further, grabbing a lobby can be just as much of a boost as upgrading Tessie herself.Skip queues, join elite matches—U4gm delivers CoD 7 lobbies instantly.
