Part 4 didn't load after when part 3 was completed, but you can get it working by hitting "Play" under the "Control" tab on your projector. The questions in part 4 will take a second or two to load, as the images in this part (as well as parts 5 and 6) didn't appear at all. The "combat similators" on part 6 will refuse to load after the time runs out on each portion, unless you hit "Play" under the "Control" tab on your projector, and it'll go to either the same portion, or to the next question, or even to the score part when you completed question 3 of the aforementioned part.

After completing the quiz, it will open a window to a now dead link.
