In town I believe the treasure will be hiding below the bank. You would have to enter through the money vault inside the bank and battle down to the bottom of the earth to capture the treasure. I don't believe Cage would be true to his word. I would have to fight him tooth and nail to get half of the earnings. Heck. Since he lied to me I would take it all. The treasure would be all the money you could possible be happy to live the rest of your life with. X marks the spot! Bring it on Cage.
