I think I might have missed security. Smartlet tells me security is east of the north-east corner. When I transfer my map from little bits of paper to a big piece of paper, I can see that there is a pattern and I am possibly missing one room where security should be. Smartlet also tells me a security code and security key for security. The latter looks like a regular expression. I didn't use these. I opened the grille and found the orange key, but I don't think I used it anywhere. Should I have used it at the north-east corner? There was no exit indicated to the east.
Yeah, security module is hidden and locked with orange key. Thats the idea. In the original way a player should not find a security module just by inspecting the station. Probably security module should not be mentioned in the smartlet. But then it become not so logical. I have to think what I can do with this.
