Supposedly this is an ARG for the Cloverfield movie sequel.
Clicking this square on the site lets you input a password.
On this square, the letters missing are A, E, G, M and N.
For the password, I tried to type "Megan," but that didn't work. "Mange" didn't work either, and neither did "Aegmn."
Quite a few new ARGs of late. List of some here:
>A, E, G, M and N.
N Game ( end game )?
Was there a character named Megan in the first film?
