Wake The Dead Ciphers

The upcoming RPG, 'BZPB: Wake The Dead,' uses an Alternate Reality Puzzle Game (ARG) to drop hints about its story. The game consists of messages from a mysterious HYDRA agent known as "Gambling-Georgian-522". So far, a handful of ciphers have been released by User:Klak as part of this activity. The solution to these will eventually be revealed, but all RPG members have been encouraged to participate in finding a solution.
