Amazon Web Services updated its Terms of Service this week. This otherwise might not be notable, but buried among standard legalese clauses about usage terms and patching policies is a hidden gem concerning the use of its new 3D game engine, Lumberyard, should the world come to a messy end.

According to clause 57.10 of the TOS:

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.

If only Rick Grimes and his crew of survivors on AMC’s The Walking Dead had been a part of the Lumberyard beta.

Should “zombie VMs” invade your data center, meanwhile, there are ways to protect yourself short of turning to Amazon’s newly released 3D game engine. Take it from industry survivor AOL.
