Halo Infinite’s Zeta Halo open-world offers a number of things to discover, ranging from unlockable armor coatings, Spartan Cores to upgrade Master Chief’s abilities, to Banished Propaganda Towers. Destroying these annoying but sometimes comedic Propaganda Towers will give you 10 Valor Points each as well as unlock the “Please Shut Up” Achievement.
