The user interface had been discarded and redone many times for the upcoming DLC. Realism must strictly not be compromised by overly helpful instructions and manual. Please wait for the release as it is still being developed. This news is intended solely as a heartbeat indicator.

The staff room has a vacant area. It will likely be filled with non-essential mini games related to problem solving. Any comments and suggestions are welcome.

Expect the DLC Advances in Cryptology 2 to release before the DLC Advances in Cryptology 1. Advances in Cryptology 2 status:

• Stochastic methods - done.
• Cryptanalytic methods - done.
• User interface - in progress.
• Story - in progress.
• Manual - in progress.

Advances in Cryptology 2 is coming soon. It is about 3DES cryptanalysis.
