Very interesting game this Merc II and thanks for the translation. Almost at the beginning of the game, in Bare island 06-05 building you find a note that tells that the four detonators have been lost at the snow island postal service. This important info is missing in the italian traslation (snow island is not mentioned). I played the EN version first a bit before starting the IT version so I could notice that but if I had started with the IT version I'd probably have been stuck there.
