God of War on PS4 introduces a surprising number of changes to the series. The latest game does away with the linear structure and progression from past games. Now you can explore an open-ended environment, earn XP to unlock abilities from a skill tree, and even acquire armor sets that improve your stats. In addition, you can collect accessories known as Talismans and Enchantments that further improve your equipment's stats and give you special perks.
