Strategy videos for Kratos and Radec were posted on the Playstation Blog, with comments by game director Omar Kendall.
On Kratos, he states:
We wanted to pay proper homage to Kratos, so the approach we took was to have his playstyle reflect some of the most iconic weapons in God of War, such as the Blades of Chaos and Apollo’s Bow. His supers revolve around his ultimate weapon, the Blade of Olympus, and we even have him grow in size to pay homage to his initial transformation in the original.
For Radec, Kendall states:
We designed Radec’s gameplay around the idea that he’s this character who controls certain spaces very well; namely, the entire horizontal space in front of him as well as the diagonal spaces in front of him. His VC32 Sniper Rifle (Forward + Triangle) and his VC21 Boltgun (Neutral + Circle) are two of his main weapons for controlling space far out in front of him.
