Techland has announced a battle royale mode for zombie slaughterfest Dying Light.

Dying Light: Bad Blood is a standalone expansion that according to Techland
will offer violent and dynamic online matches that blend PvP and PvE styles of gameplay.

Here's how a Bad Blood match works:

You and five other players are dropped into a hostile, zombie-infested area. Each of you has the same goal: to evacuate before the night falls. Use your parkour skills to swiftly traverse the city, scavenging for weapons that will give you an edge over your opponents. But remember, the clock is ticking.

To pay for a seat on the extraction chopper, you need to harvest blood samples from the infected. Form dynamic alliances with other players to get tactical against formidable zombie bosses - and then turn on your allies to steal their samples. In a cruel set-up where everyone fights for the survival of the few, betrayal is not a question of “if”, but “when”.

The more samples the players harvest collectively, the more seats are unlocked. But everyone pays for their seat individually, which means the alliances are short-lived and can easily end with a stab in the back. Make sure you have enough evacuation points once the chopper arrives, and don’t get killed as you race to the extraction zone.

Sign-ups for a global playtest of the new expansion are available now, and Bad Blood will launch in 2018.

"Our aim is both to satisfy players’ demands for competitive PvP gameplay and to explore new directions for Dying Light’s multiplayer experience,” said Techland producer Tymon Smektala.
