The best one is the ability to barricade doors, though, which offers an extra bit of roleplaying potential for those who don't just want to pit a zombie horde against their Dragonborn.
There are some really nice subtle touches in this mod, too. The player gets to control how the zombie outbreak plays out, and in a sandbox world like Skyrim, that means untold amounts of chaos and violence. This mod offers a variety of different zombie outbreak scenarios, each with different settings that can be customized at any time. That's what 28 Days and a Bit 5 – Zombie Mutation is for. Sure, there are Draugr basically everywhere, and a few quests that are concerned with necromancy, but there's nothing like a full-fledged zombie breakout waiting in the wings, just underneath the surface of Skyrim's world. Another popular fiction trope that Skyrim only touches the edges of, however, is the zombie.
