While this might look like a rehearsal for an upcoming superhero movie, it's actually a working concept for a suit of armour built by Sydney company Chiron Global. Armour that's been designed not for show, but for sport.
The company is floating an idea called Unified Weapons Master, which essentially wants to be a weapons-based version of MMA. Combatants wear the suit, which protects them from all sorts of impact injuries, and in doing so they're able to bring weapons into the fight and just go nuts with them.
Teaser videos even show that the suits are "smart", in that they register hits and are thus able to keep score.
I would watch this, and play the inevitable EA Sports cash-ins, until the end of time.
