If you’re really looking to make a mark in Black Ops 7, you’ve probably heard whispers about the Ol’ Tessie Abomination Upgrade. This isn’t some basic paint job or a tiny speed bonus—it turns your rugged little ride into a map-controlling beast. Players who love using vehicles to smash through objectives or make a big entrance will feel right at home with it. It’s pure muscle, both in firepower and durability. I know a lot of folks are quick to look for quick routes like CoD BO7 Bot Lobby, but this one’s worth earning step-by-step—the upgrade’s just too good to skip the grind.

First thing you’ve got to remember—you can’t dive straight in. You need the first-tier Ol’ Tessie upgrade already installed. No way around it. That means knocking out whatever missions, side quests, or challenges stand in your way so you can bolt that initial kit onto your vehicle. Once that’s done, you’re set for the real hunt.

Your target is a unique mini-boss zombie folks call “The Cook.” You’ll find him lurking around Exit 115, and it’s rarely quiet there. Honestly, bringing a squad makes things a lot less messy. The Cook soaks up damage like a sponge and has a few nasty surprises up close, so pack your high-damage gear. Before he shows himself, expect waves of smaller undead crawling all over the place. Work your way through, drop The Cook, and be ready—he leaves behind a freezer key you’ll need. Easy to overlook with all the chaos, so check the ground before you move on.

Once you’ve got that key, head to the diner near Exit 115—it’s hard to miss if you stick to the main road. Inside, find the big freezer. That’s where the key gets used. Pop it open, and there it is—the Abomination Carcass. Looks grim, but it’s the heart of the upgrade. Grab it and keep it safe because now you’re headed to the last stop.

The final stretch takes you to the Ashwood garage, tucked into that industrial area on the map. Roll in with Ol’ Tessie and use the upgrade station. There’ll be an option to install the carcass right into your ride. Doesn’t take long, and the change is instant—your Tessie’s now a nightmare for anyone in your way. Sure, people hunt for shortcuts or even try to buy BO7 Bot Lobbies, but with a quest that’s this fun, blasting through it yourself just feels better. Once you’re done, roll out and let the map know you’re not here to play nice.
