There are so many mods for Zomboid, some of them are staples that never leave my modlist. I have a mod that replaces almost all the headgear on zombies with a headcrab from Half-Life (you can loot and wear the headcrabs too), as well as a couple “occupations” based around a Black Mesa security guard, or an HECU marine.

There’s the whole host of True Music add-ons, which all add actually listenable music to the game, in the form of cassettes, records, or CDs. There is also a collection of mods called True Action, that give you more emotes and animations for your character, such as dancing or actually sitting on a chair or bed instead of just the floor. Tons of vehicle mods too; plenty of real-life vehicles from all kinds of eras (the game takes place in the 90s, so I usually like to keep the 90s aesthetic) but there are plenty of “lore-friendly” ones that have made-up names for the cars. Mods that add interiors to RVs so you can have a mobile base, mods that make you able to add a basement to your house/base, new maps (one I have called Project Russia, and it’s basically the surrounding area outside Moscow, also a huge map)…
