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]
Survival mode in tower defense games
Rampart, released in 1991, is the first prototypical survival game mode in tower defense games.[5] Survival mode is particularly common among tower defense games, such as Plants vs. Zombies.[6] where the player must improve the defenses of a specific location in order to repel enemy forces for as long as possible.[7]
Many sandbox games, such as Minecraft, take advantage of this game mode by having players survive the night time from a variety of monsters, such as skeletons and zombies.[14] Another sandbox game, Rust, uses both non-player characters and other players as enemies, inviting player vs player combat in order to survive in the game's environment.[15]
