The Dying Light 2 announcement at Microsoft's E3 press event was made significantly cooler by the surprising news that cold fusion-powered RPG writing machine Chris Avellone is working on it. As we said in our report, Avellone's participation "signals a significant evolution for the series" by giving it a much greater focus on narrative and outcomes. 

But Avellone isn't the only talent working on the game. "We also got some additional help in the form of the former The Witcher 3 writing team," Techland told VG247. "Those guys were responsible for some of the best quests from that game including the Bloody Baron quest line. All of those guys are working very hard to create a narrative—it’s like a puzzle to play with."
