Techland announces plans for a free content update for Dying Light, saying this will add a new Hard Mode to the zombie game along with other changes. They don't specify when this will be released, but say it will be the first of several free content updates. Here's word:

As a part of its long-term support program for Dying Light, Techland today revealed the first details about upcoming new content for the game. Several free content updates will be released in the coming months to ensure that all Dying Light players can find new experiences to enjoy. The core highlight of the first update will be the frequently requested Hard Mode.

"A few gamers have already finished Dying Light and are asking for more. So we’re going to give our community a new challenge that will put everything they learnt in the game to the test. Hard Mode is exactly that. We’re aiming to have it out around the start of March, if not sooner. Depends on how brutal we wanna make this on people" – Tymon SmektaBa, Producer.

Hard mode will feature various changes to the gameplay, including: ramped up nighttime difficulty, deadlier and more vicious foes, increased need for stealth and silence, scarce resources and supplies, & plenty of other additions. The first content update will also bring many improvements to the gameplay and a number of new character outfits. The update will be available on all platforms in the near future.
