Character class
In tabletop games and video games, a character class is an occupation, profession, or role assigned to a game character to highlight and differentiate their abilities and specializations.
In role-playing games (RPGs), character classes aggregate several abilities and aptitudes, and may also detail aspects of background and social standing, or impose behavior restrictions. Classes may be considered to represent archetypes, or specific careers. RPG systems that employ character classes often subdivide them into levels of accomplishment, to be attained by players during the course of the game. It is common for a character to remain in the same class for its lifetime; although some games allow characters to change class, or attain multiple classes. Some systems eschew the use of classes and levels entirely; others hybridize them with skill-based systems or emulate them with character templates.
In shooter games and other cooperative video games, classes are generally distinct roles with specific purposes, weapons, or abilities, with only tangential relation to the RPG context. Their differences may range from simple equipment changes, such as sniper classes armed with sniper rifles, to unique gameplay changes, such as medic classes that are tasked with healing and reviving injured allied players.
