No one wants to — and virtually no one does — read the lengthy, legalese-filled user agreements. But for those who do choose to plow through the mouseprint, Amazon has left an amusing zombie-flavored treat in one of its contracts.

CNet reports that the terms of service for Amazon’s new Lumberyard games development engine were updated on Monday, detailing restrictions on how consumers can use the program.

Lumberyard, which is free, allows users to create 3D, high-quality games connected to Amazon’s Web Services and Twitch.

Under the terms for the service, Amazon notes that the program is 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.”

All of those restrictions go out the window, however, if the Centers for Disease Control and Prevention declare the presence of a “widespread viral infection transmitted by bites or contact with bodily fluids that cause human corpses to reanimate and seek to consumer living human flesh, blood, brain, or nerve tissue and is likely to result in the fall of organized civilization.”

In other words, if the zombie apocalypse happens, you can use the Lumberyard engine for whatever your heart desires.
