The player character, Alexios or Kassandra, is a greek mercenary, and a descendant of the Spartan king Leonidas I. They inherit his broken spear, which is forged into a blade to become a weapon that grants the player special abilities in combat. The game uses a skill tree system that allows the player to unlock new abilities. The three skill trees are "hunter", which focuses on ranged attacks through use of a bow & arrow, "warrior", which focuses on weapons based combat (swords, spears, axes etc. ), and "assassin", which focuses on stealth & silent take-downs. This replaces the system used in Origins, which granted the player a series of passive abilities.
