How to unlock the rest of the SCPs?

[shroobi]

Like in the tiel, how do I unlock all of the SCPs? I've finished 5 of them and chose (to avoid spoilers) the right option . I've been given a prompt that now all of the SCPs are unlocked and I can play them in any order, but it didn't unlock anything and 4 of them are still locked. What am I missing? Was there any choice in-game to play the rest of the stories?

The reason four is still locked is because I think there would have been more, but sadly, the development got shut down. Great game, but too short.
