SiN Episodes

Planned as an episodic sequel to SiN, set 4 years after the end of the game, only 1 of the planned 9 episodes was released. The episodes were to be playable in any order, with independent storylines, a planned playtime of 4-6 hours and an overarching story. Originally, a development cycle of 4-6 months was planned between each release to allow future episodes to change depending on what players had done in the previous episodes. To this end, certain game data was recorded and could be uploaded anonymously by players at any time. This information included game options such as difficulty level, support level and cheat usage, as well as statistics such as weapon-specific kills, deaths per map, secrets found, time to completion and high scores for those playing in Hard Corps mode.
