Could a demo of Dying Light be released on Xbox One or PlayStation 4 tomorrow? Warner Bros. won't say - but a new tease from the publisher suggests some big news is on the way for the open world zombie survival game.

In a tweet posted on the official Dying Light twitter account last Friday, the publisher said: "February 11 will be the day of trial for all humanity. Save the date!"

A teaser video released alongside the tweet (above) also states: "The outbreak will change everything. Are you prepared? Are you truly prepared? Feb 11, 2014."

The words 'Everything', 'Prepared', and 'Truly' are also highlighted in orange. Think you've cracked what it all means? Speculate away in the comments below.

Dying Light launches on Xbox One, Xbox 360, PlayStation 3, PlayStation 4 and PC later this year.
