Survival mode is a video game mode in which the player must survive the game for as long as possible while the game sends waves of challenges to the player that become more difficult with each subsequent wave. Another variant of the mode requires that the player reach a certain point before losing the game. The mode is particularly common among tower defense games where the player must improve the defenses of a specific location in order to repel enemy forces for as long as possible.
