Unwinnable states are not fatal in games that utilize checkpoints or are divided into levels in which progress cannot be saved midway through one, allowing players to reload a checkpoint or restart the level to reverse an unwinnable situation. However, in other games, softlocks may cripple or corrupt save files, forcing the player to start completely anew from the very beginning of the game in order to get further in the game. For example, in games such as Goldeneye 007, Perfect Dark, and TimeSplitters, the level does not end once a player fails an objective short of being killed, but it is impossible to progress to the next level no matter what the player does afterwards.
