Survival mode

Survival mode, or horde mode, is a game mode in a video game in which the player must continue playing for as long as possible without dying in an uninterrupted session while the game presents them with increasingly difficult waves of challenges.^[1] A variant of the mode requires that the player last for a certain finite amount of time or number of waves, after which victory is achieved and the mode ends.^[2] Survival mode has been compared to the gameplay of classic arcade games, where players face off against increasingly stronger waves of enemies.^[3] This mode was intended to give the game a definite and sometimes sudden ending, so that other players could then play the arcade game as well.^[4]
