Far Cry 5's next expansion, Dead Living Zombies, will launch on August 28, Ubisoft has announced. The expansion sees players meet up with "D-tier" film director Guy Marvel who has a number of ideas for an "epic zombie saga." You will play seven different "film scenarios," which are maps made using Far Cry 5's Arcade Editor tools.

As you'd imagine, you will be fighting against "hordes of undead" in all manner of different environments. Once you beat each map, you'll unlock a Score Attack mode. If you get a 3-star rating you'll get weapons and gear that you can use in the story mode.
