In the UK you have to have pre-ordered the game to play the beta HOWEVER, The Call of Duty: WW2 beta is free to download from the Hong Kong PlayStation Store. All you need to do to is sign up for a Hong Kong PlayStation Network account, which takes two minutes.

“Beta participants will experience the all-new War Mode where players compete against each other in objective-based, team gameplay,” reads the PlayStation Store description.
“As a critical stress test of our systems, the private beta will also enlist players in fast-paced, grounded Call of Duty action on maps set in World War 2 locations such as Pointe du Hoc and the Ardennes Forest. Team up with your friends to compete in fan-favorite modes such as TDM, Domination, Hardpoint, and more.”
The download does not require a pre-order or code.
The bad news: The beta runs from 26th August (6pm BST) until 28th August (6pm BST). The Hong Kong beta dates are shown as a day later but that’s due to their time zone being seven hours ahead of us so, don’t panic, players should still get access at the same time as others in the UK.
