9. Crimson Heads

First appearance: Resident Evil (2002)

Crimson Heads were one of the best new features in the Resident Evil remake.

These deep red zombies are born after a previously defeated undead undergoes the V-Act process and rises back up to continue their hunt for human flesh.

There just aren’t enough bullets to kill every zombie twice, so you’ll have to plan ahead and choose which zombies to kill in the first place.

You can also burn the bodies with gasoline or an incendiary grenade, but even the best of us are bound to miss a few.
