Everyone who plays the ongoing Call of Duty: Black Ops III multiplayer beta on PlayStation 4 will receive a free theme focused on the franchise’s famous Zombies mode, Activision announced today. No code is required to get the theme. Take a look at the theme through the images below.

The Black Ops III multiplayer beta began August 19 and runs through August 23. Previously, you had to preorder the game to play it, but now it’s open to everyone.

As announced previously, PS4 players get to try the beta first as part of Sony’s new exclusivity deal with Activision. Xbox One and PC users will get to play August 26-30. The beta, the first Call of Duty public beta in years, will not be held on PlayStation 3 and Xbox 360.

The Black Ops III beta included seven maps and three modes at launch, and more have since been added. You can read more about what each mode entails and the file size here.
