And it’s kind of disappointing. WARNING: This is going to contain a lot of nerd jargon, so non-Halo fans click away.
The MJOLNIR armor is connected to the wearer through a neural implant in the wearer’s brain which jacks into the helmet, allowing the wearer to link with the suit and operate as one.
In Halo 5: Guardians, and any other Halo game where a Spartan is wearing the MJOLNIR armor without the helmet, they’re still able to operate the suit normally, as if they still had that neural pathway closed. Shouldn’t the 1,000 lb titanium suit become extremely difficult to move even for a genetically-enhanced super soldier?
