The above picture I took is one such random encounter, that would go towards the 'Help brave survivors slay the undead' part of the event quest. After doing this mission we will be able to receive. The blueprint is in a building next to the antenna and you can get to it while completing the 'Prodigal Son' side mission. The blueprint is in one of the rooms on the inns upper level.
If you've played Dying Light before, you would have come across the type of encounter many times already. The blueprint is inside one of the huts in the fishermens village. Neither of which are difficult to find, just run around for a few minutes and you will get a little map notification that people need some help. The other new event quest will require you to save some helpless people from monsters and bandits, help some survivors in their fight against the undead (both parts need doing twice) and that will reward you with a Zweihänder Sword. One of the event quests needs you to take two airdrops from Rais' men, this will reward you with a Agatha Medieval Shield. Running until December 16, this event has some new random encounters available as you travel through either the Slums or Old Town. Things are getting a bit medieval in Dying Light, with a new Chivalry crossover event that's arrived with some new free goodies to grab.
