Amazon has its own open source software for building 3D video games, called Lumberyard. In the service terms it states what you can and can’t do with it. One of these things is that you aren’t allowed to use Lumberyard with critical medical devices, unless of course it’s the zombie apocalypse.
You read that right, Amazon has built into their contract that there are specific things you can’t do with Lumberyard involving safety-critical systems. Unless the “Centers for Disease Control or successor body” declares that a zombie virus has been unleashed. Then you are legally free to use the system in a ton of ways that you aren’t normally supposed to, like for air traffic control, life-critical systems, autonomous vehicles, live combat, and more.
The AWS Service Terms section 57.10 says, “Acceptable Use; Safety-Critical Systems. Your use of the Lumberyard Materials must comply with the AWS Acceptable Use Policy. The Lumberyard Materials are not intended for use with life-critical or safety-critical systems, such as use in operation of medical equipment, automated transportation systems, autonomous vehicles, aircraft or air traffic control, nuclear facilities, manned spacecraft, or military use in connection with live combat. However, this restriction will not apply in the event of the occurrence (certified by the United States Centers for Disease Control or successor body) 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 organized civilization.”
So if the zombie apocalypse rolls around the corner and you just happen to have Amazon’s Lumberyard, you don’t have to worry about any legal ramifications as you use their game engine to save the world. It is a small bit of humorous text hidden in a long legal document, and it is sure to help Amazon spread the word about their new open source software for making video games.
