Weapon of Rock Step-by-Step Guide:

Step 1: Insert 3 red coins in the souvenir machine of Kepler System. Coins are dropped randomly by zombies.
[PART 1 UNLOCKED]

Step 2: Buy Gold Teeth for 300 tickets (from arcade room in Journey into Space distrcit). You get tickets from playing arcade games and beating challenges.

Step 3: Lure a Brute into the Alligator Trap (Kepler System). This will make the alligator’s teeth fall out. Brutes spawn in rounds 10-12.

Step 4: Replace the alligator’s teeth with the golden ones. Hold Square (PS4) / X (XB1) near the alligator trap.

Step 5: Go to Polar Peak district, in the outside area where the water fountains are. Use the sunglasses that turn the screen black&white (they are a random drop by zombies). Now you can see a boat in the water. There’s a small item on the back of the boat that you must shoot off.

Step 6: Grab the boat item (that you just shot off) from one of the water fountains
[PART 2 UNLOCKED]

Step 7: Go into pack-a-punch room. Interact with the UFOs on the table to activate them. When done correctly they will fly out the portal.

Step 8: Use the Chromosphere Trap in Kepler System to kill 30+ Zombies. Make sure a UFO is flying around the trap! If it’s not here you haven’t done the last step correctly.

Step 9: After getting enough trap kills the UFO flies around Kepler System. Purchase the Arcane Core for 300 Tickets (found in Kepler System) and kill zombies with it near the flying UFO. It will suck in some blue orbs when done correctly.

Step 10: After killing the UFO has absorbed enough souls it will drop a flame core. Pick it up. Now Shoot the box inside the alligator trap with the flame core (where you placed gold teeth). Quickly run to the box, pick up the last part and exit the trap before it kills you.
[PART 3 UNLOCKED]

Step 11: Head to the underground area. There’s a sign where you must place all 3 parts to build the weapon of rock. Trophy unlocked!

And that’s it. You’ve now unlocked the Weapon of Rock, a.k.a. “Shredder”. Enjoy this beautiful one-hit-kill weapon.
