This video from Techland offers a teaser of what to expect from future add-on content for Dying Light, their zombie game. This is accompanied by an open letter from Paweł Marchewka, the CEO of Techland on the same topic. Here's the open letter:

Dear Dying Light Fans,

I would like to take the time to send out a sincere thank you to all of you for your trust, support, and interest in Dying Light. Without you, our game could never have become such an incredible success. We are all extremely grateful and impressed by the passion and creativity you showed us. This is why we just released a new content update that each of you can enjoy completely for free. We also want to assure you this is just the start of what we will be bringing you in the Dying Light world.

We want to especially thank those who finished the game and are sending us their comments, suggestions, and recommendations. We are listening to all of them and are working to incorporate as much of your feedback as possible. You can already see a part of it in our ‘Hard Mode’ patch and this is just the beginning, as there is much more to come.

We want to hereby promise we will be actively supporting Dying Light with original content, such as new maps, modes, skills, quests, weapons, and much more. Everyone who downloaded the latest update, you can find a sneak peek of what is coming by accessing the main menu of the game. We have plenty of new content in the works, so try your hand at the new Hard Mode and stay tuned for more.

-- Paweł Marchewka, Techland CEO
