So this is a very pleasant surprise. Dying Light, a game that was released in January of 2015, is set to receive a further 10 pieces of downloadable content over the next 12 months.
PCgamesn is reporting that the first pack will contain new enemy types and is set to release "very soon", with later DLC even packing in new story missions.
Dying Light received a large expansion titled The Following in early 2016 and it was assumed that this was the final piece of extra content to be released, but clearly not. This is excellent post-launch support from developer Techland, and we'll have more details for you when we hear what other content is coming for the zombie hit.
