Halo Infinite's campaign has plenty of collectibles to find. This includes Audio Logs, Skulls, Armor Lockers, and Broadcast Towers. Finding these banned propaganda tricks can take a while, but if you listen to them, it will make things easier.
There are 40 Banned Propaganda Towers to find. They are spread across Zeta Halo. They appear as towers with a fusion core at the bottom. Players will need to destroy the power source to mark them as complete. Here are the locations of the 40 propaganda towers banned from Halo Infinite.

There are plenty of Banned Propaganda Towers to find and destroy. We recommend starting from the northernmost point of Zeta Halo and working your way down. Alternatively, a flying vehicle will allow you to quickly get to each of them. You don't even have to go out to destroy them if your aim is good enough!
