Trudge back to the Harran Stadium and test your parkour might in a “series of sadistically challenging puzzles” in Dying Light’s biggest DLC pack, The Bozak Horde.

Available now for season pass owners and separately for $9.99, The Bozak Horde focuses on co-op gameplay and good old competition. Players can now compare their scores to other survivors with online leaderboards, and the competitive elements allow players to “experience Dying Light in completely new ways.”

The Bozak Horde includes:

Brand new game mode – run through Bozak’s challenges in Harran Stadium compete with others to climb the ranks of the Dying Light leaderboards

Brand new map – traverse Sector 0, home of Harran Stadium and the sight of the government’s first loss against the zombie horde

Ultimate Co-op challenge – Three friends are almost a necessity to pass through Bozak’s crazy courses, so grab a few buddies!

Brand new weapon – Unleash your inner hunter with the Stealth Bow, and equip yourself with electric, incendiary, and exploding arrows

Dying Light was developed by Techland and released to the Xbox One, PlayStation 4, and PC on January 27, 2015.
