Call Of Duty: Infinite Warfare -- The Shredder Wonder Weapon
Shredder is an energy pistol that annihilates zombies with a swarm of mites. It is best used at the early stage of the game when the number of zombies are still manageable. Shredder can only be built in three steps: (1) get the battery, (2) get the souvenir toy, and (3) get the gems.
How To Build Shredder Step 1: Get The Battery
To get the battery, head over to the log flue ride. It is recommended that you wear the shades. Once you get there, the battery is floating right at the rear part of the boat. Toss a grenade into the log flume ride and shoot until you see the battery is being hit. Once done, go to the pathway that will lead you to the area with green and purple water sprouts. In a matter of a minute, you shall see the battery surface from the water jets. Get the battery immediately before you'll regret what will happen next.
How To Build Shredder Step 2: Get The Medusa Toy
To get the souvenir toy, you have to stay around Kepler System and kill off zombies until they drop red coins. You need to insert three coins in the Souvenir Machine for it to let out the Medusa Toy. Take note that you will need to insert one coin only at a time because you cannot hold more than one coin. Once the third coin is already inserted, Medusa Toy will be released.
How To Build Shredder Step 3: Get The Gems
Lastly, to get the gem, you need to have access to the Black Hole portal to get you to the PAP machine. Interact with the purple jar UFOs will seed and hover around the area. You will need 30 zombie kills utmost through the Steel Dragon trap. Once done, the UFOs will start spreading. Now purchase the Arcane Core for 300 tickets at the concession stand. Go back to the PaP area and accomplish 20 kills using your weapon with the Arcane Core accessory to direct collected souls towards the UFOs. Once done, the UFO will drop a glaring ball of light which is necessary to morph your weapon with an ice capability.
At the arcade counter, buy the Gold Teeth for 300 tickets. Proceed to the Kepler System and stuff a Brute inside the crocodile's mouth. Let it close it so its teeth will break down. You have to replace it now with the Gold Teeth and shoot down the panels in the crocodile's mouth. Go back to the Polar Peak, visit the small cardboard cutout to get the Shredder Wonder Weapon.
