Security Breach is often regarded by fans to be the only game that lacks any actual story due to not much happening during gameplay. This is actually a misconception, though the game is at fault for not making it apparent because it was executed very badly for a free-roaming title. Apparently, part of the problem is that Scott was not directly involved nor credited at the story writer, which caused Ruin to fix most of the issues SB brought to the table.
Even without the DLC, SB the most story-rich game in the franchise by far. If you put any of the game lore in another FNaF title, it would be too much. This is because SB's method of storytelling is vastly different from the other games. SB is the only game that features several sub-stories, though it's understandable that they were skimmed over because they don't seem to have any real relevance to the main protagonists and antagonists.
In this section, all the contents in SB will be put into several sub categories. Ruin's DLC will also be put into their own categories.
