Blood Zombie

This variant spawns during a Blood Moon and at no other time, so the encounter is a night you either brought on or got handed. It behaves like a normal zombie in the ways that matter for base design: it walks toward you, works its way around obstacles, and opens unlocked doors on the way. There is no armed version, and Expert does not add one.

From across the screen it plods, which is exactly the trap. The closer it gets to you the faster it walks, and by the time it arrives it is moving quicker than anything else on the ground that night. Expert raises both ends of that scale. The usual habit of backing away while chipping at zombies fails here: retreating just hands it the distance it wants. Kill it before it closes or stand and swing, but do not kite it on foot.

For a base, remember that Blood Moon zombies already work doors, so a door is not a wall. This one reaches it first and hits harder when it does. Platforms above head height, or a wall with a firing slot, are worth building before the night you need them.
