Techland's Dying Light is a quality zombie-bashing simulator with a big open world. Player Unknown's Battlegrounds is this year's sleeper hit, coming out of nowhere on Steam Early Access to dominate the sales and 'most played' charts. Someone at Techland has been playing PUBG.
Next year Dying Light will receive a new expansion, Bad Blood, which is going to be a battle royale mode. The base game already has all the elements required in place, bar one – PvP. Dying Light had co-op multiplayer, and even a Left 4 Dead-inspired mode where players could control powerful zombies in other players' worlds, but the core of battle royale is players killing players. It remains to be seen whether the game's style suits this kind of play, but Dying Light's movement in particular is well realised, so this could turn out surprisingly well.
“Our aim is both to satisfy players’ demands for competitive PvP gameplay and to explore new directions for Dying Light’s multiplayer experience,” said Tymon Smektala, producer at Techland, while playing PUBG. “Since Bad Blood was inspired by fan requests, we want player feedback to be an integral part of our development. That's why we’re inviting Dying Light fans to take part in our Global Playtest.”
Presumably 'fan requests' means sales receipts. The standalone expansion launches in 2018, and you can sign up for the pre-launch playtest here.
