Call of Duty: Black Ops 4 is set to launch Friday, October 12 for PS4, Xbox One, and PC. If you're a fan of the series, you probably already knew that, but what you might not know is that PS4 owners can pick up some nice Black Ops 4-themed freebies. In fact, you don't even need a PS4 to take advantage of some of them.

All of the free items can be collected from PlayStation's Call of Duty: Black Ops 4 Countdown to Launch page. Here you can click links to get several things. For one, between now and October 11, you can enter to win one of three PS4 Pro consoles that come with a physical copy of the game and are packaged in a massive Black Ops 4 shield tin box.

Next, you can scroll down to claim codes for Black Ops 4 PS4 avatars, as well as a dynamic Black Ops 4 PS4 theme. You can redeem these codes on the PlayStation Store, either in a browser or on your PlayStation 4 console itself.

The theme gradually cycles between images of different specialists from the game, giving each one the slow-zooming "Ken Burns effect" treatment. The theme also tints your system icons Black Ops orange. Finally, the Countdown to Launch page also offers a selection of wallpapers for desktop and mobile devices that anyone can download, even those without a PlayStation account. One set of wallpapers is based on Zombies mode, while the other features the new battle royale-like Blackout mode.

Call of Duty: Black Ops 4 will ship with the two modes mentioned above, but without a standard campaign like the ones found in previous installments. Instead, you'll find a selection of single-player challenge missions that are intended to help sharpen players' skills. In addition to the content that ships with the game, developer Treyarch has a good deal of free post-launch DLC lined up to keep players coming back.
