It seems that the first question or clue is:
WOULD YOU LIKE TO KNOW MORE?
PLEASE DO THINK TWICE BEFORE ANSWERING...
The second one seems to be:
WHO IS HE?
USE HIS FIRST SYMBOL...
The third clue or question seems to be:
WHAT DO THESE NUMBERS MEAN?
And the fourth one seems to be this one:
WHAT DID DRUSUS SEE?
TACITUS, GERMANIA, 34...
In the background, this video is really weird, and the sounds and music are also very weird.
WTF is this??
