BioWare Reveals a Third Clue About Next Game

BioWare's Facebook page has been updated with yet another barcode, and as per usual it was quickly decoded and discovered to be the URL for the website of the British Secret Intelligence Service. Are the clues making sense for you yet?
1) 55.845 is the atomic weight (Ar) of iron, a component in steel. This might point toward Shattered Steel, a 1996 BioWare game about giant mechs.

2) -128.5 Fahrenheit, the lowest recorded temperature on Earth, a record held by Vostok, Antarctica. Vostok 1 is the humanity's first manned space flight and also the name of a system in Mass Effect.

3) URL for the S.I.S. or Secret Intelligence Service.
Meanwhile, Kotaku is fielding the rumor that the upcoming project is a multiplayer Mass Effect spinoff.
