Attack of the Radioactive Thing transports players back to the 1950s, where they’ll have to dodge Willard Wyler’s nefarious zombie hordes while dealing with horror movie madness—like a giant monster off the coast. Don’t worry, though, there are plenty of new weapons to make use of, and in this article we’ll show you how to find and use all of the pieces needed to build the Seismic Wave Generator in Zombies: Attack of the Radioactive Thing, a new weapon included in the game.

It should be noted that you will need to take each of the blueprints and parts mentioned in this article to a blueprint bench. These can be found scattered around the level, so just look for one until you spot it. It shouldn’t take you too long.

How to Build the Seismic Wave Generator

Finding the first piece of the puzzle isn’t that hard, and players can look for the blueprint needed to build the Seismic Wave Generator by heading to the retro restaurant shop, which is the same place that you find Elvira’s spellbook when you’re trying to learn how to activate the Pack-a-Punch.

Search behind the shop and then, with the blueprint in hand, make your way over to the workbench and drop the blueprint onto it. Now you can start collecting the parts that you need to build the Seismic Wave Generator.

The first part that you need to find is just behind the building where you got the blueprint. Look around for a coil near where you picked up the Seismic Wave Generator Blueprint, and pick it up to collect it. Now, return to the table and drop it in.

The second piece you need to find is an old rod. This item can be found on the red bench nearby. It stands out pretty easily against the more standard hues that make up the buildings, so you shouldn’t have too much trouble finding it. With the rod collected, drop it into the workbench before you continue.

The third and final piece that you need to complete construction of the Seismic Wave Generator is the capacitor unit. This item can be found in the parking lot nearby. Look for the line of port-a-johns and look for this item on the ground beside the first one.

Once you have all three parts, interact with the workbench to complete construction of the Seismic Wave Generator. You can use this weapon to blast zombies up into the air and kill them, and it’s very useful for clearing out large groups of zombies.
