It was only yesterday that we reported on Amazon's swish new Lumberyard game engine.

However, something sinister has since been uncovered deep within the software's terms and conditions (via PCGamesN)

You might want to sit down for this...

Turns out there's a clause in there that prevents people using Lumberyard when it could endanger life... unless there's a zombie apocalypse, that is.

Does Amazon know something we don't?

Here's what's tucked away in clause 57.10 "This restriction will not apply in the event of the occurrence of a widespread viral infection transmitted via bites or contact with bodily fluids that causes human corpses to reanimate and seek to consume living human flesh, blood, brain or nerve tissue and is likely to result in the fall of organised civilisation."

It's very specific. Hopefully we'll all be too busy playing shiny new Lumberyard games to notice the dead clawing at our doors.
