Infestation: Survivor Stories is an online, multiplayer, survival-simulation game set in an open world infested with zombies. Players are thrust into this post-apocalyptic world five-years after a viral outbreak that ravaged the human population and left, in its wake, a nightmare of epic proportion.

The War Z has officially changed its name to Infestation: Survivor Stories today, in part to help fans differentiate the popular game from similarly titled brands.

OP Productions initially filed The War Z trademark early last year, but soon found out from the United States Patent and Trademark Office that the name was comparable to another property. After months of trying to resolve the issue, OP Productions decided the best option to avoid confusion among players was to rename the game. Current players will not experience any change or interruption with the exception of the change in name and game logo.
