Zombie Exodus: Stronghold Sneak Peek (Patreon)

In the next chapter of ZE: Stronghold, there is a huge Easter Egg, and I thought I would give a sneak peek.

Can you tell what the image above references?

For those of you unable to see the image above, this should give you a hint…

As you thread your way through the impending darkness of the tunnel, a low, haunting melody traces its way to your ears, as if carried on the wind itself.

Ring-a-ring the rosie,
A pocket full of posies,
Ashes! Ashes!
We all fall down.
