Paradox Junction looks familiar for about five seconds, then the map reminds you it's running on broken time. You'll be swapping eras, dodging angles that weren't there a round ago, and trying not to get pinched by sprinters in the cul-de-sac. If you're practicing routes or just want a calmer warm-up before you commit to high rounds, a cheap CoD BO7 Bot Lobby can help you get your hands steady, because building the Blundergat isn't hard, it's just easy to mess up when everything's on fire.

Step 1: Barrel from the humming Loot Cyst

Start in the future, the "nuked" side. You're hunting the green Loot Cysts, but not any random one. You want the cyst that's making that low hum, like it's alive (yeah, gross). Once you've found it, don't wander off. Train a small group and get kills right on top of it. You'll know you're doing it right because it reacts as you feed it. Keep going until it bursts and drops the Barrel. Grab it fast, then reset your loop before the map decides to spawn something spicy behind you.

Step 2: Hammer via acid, mannequins, and a quick time hop

Next is the Hammer, and it's the part that wastes the most time if you're not focused. First, grab the vial upstairs in the yellow house. Then head to the green house kitchen and use the setup there to mix the acid. Once you've got it, swap back to the past. Now look for intact mannequins only—if it's already smashed, ignore it. Hit the mannequin with the acid to melt it down. You'll usually find good targets near the cul-de-sac lanes or close to the Pack-a-Punch area. After melting, return to the future and check the spot for the Hammer. If it doesn't appear, don't panic; roll the round and try the interaction again until it finally drops.

Step 3: Sealant on the shelf, Stock behind the "shimmer" wall

The Sealant is a gift compared to the Hammer. Go to the past version of the yellow house and look on a bookshelf. It's the sort of thing people sprint past because they're thinking "quest step," not "tiny item on a shelf." The Stock is trickier but fair. In the future, listen for a shimmering audio cue near those black growth patches on walls. When you find the right one, remember the exact location, then jump to the past and blow open that same wall with an explosive. Swap back to the future and the Stock should be waiting where the wall used to be.

Build spot and why it's worth it

With all four parts, head to the big truck in the middle and pay the Essence to get inside. The workbench animation leaves you exposed, so don't be a hero—have a teammate watch the doorway or toss something to buy space. When it finishes, you've got the Blundergat, and it immediately changes how safe your rotations feel. If you're planning to push deeper, Pack-a-Punching into the Sundergat is the real payoff. As a professional game currency and items platform, U4GM is convenient and reliable, and you can buy u4gm CoD BO7 Bot Lobby to tighten your practice runs and make the grind less of a coin flip.
