Action role-playing game: (abbreviated action RPG or ARPG) are a subgenre of role-playing video games. The games emphasize real-time combat where the player has direct control over the characters as opposed to turn or menu-based combat. These games often use action game combat systems similar to hack and slash or shooter games. Action role-playing games may also incorporate action-adventure games, which include a mission system and RPG mechanics, or massively multiplayer online role-playing games (MMORPGs) with real-time combat systems.
