Once Human is all about surviving zombies, opening crates, and improving your gear back at the base, as long as you’ve got the required materials.

You’ve braved rundown buildings, schools, and hospitals in Once Human and still can’t find a single Fireproof Plastic. Though the grind is enough to burn out any player, you really need to find this material if you’re looking to craft that Intermediate Gear Workbench and all those fancy tier three items.
