a proper introduction to the SCP foundation
When you first boot up the game there should be a diffirent simple menu maybe just like a black screen with two options: start game and quit. When hit start you'll be asked to adjust the settings like brightness and ect. After adjusting the settings an introductional video of the SCP foundation will start.
This video would be like an introductional/training tape made for new foundation personel explaining what the foundation is, what it does, what the SCPs are, the object classes, personel classes (D-class, MTF, researchers) and ect. all the basics.
This video could be voiced by Volgun with his Dr. Miller voice and would have some simple illustration to go with it.
After the video you'll end up in the actual menu.
