Remove the third brackets, the third brackets [] is used for formatting and showing what should be written.
The proper command would be "port connect 10.10.0.1 shootandkill"
I don't know, it's probably not my cup of tea, I connected to the server removing the brackets and I tried to figure out password for the different users, I tried the birth date of the chief in all the different possibilities and it didn't work.
The game is really well made and I like the concept but it is too hard for me.
