People who have played ARMS know that Max Brass, the new playable character being added to the roster tomorrow, isn’t the only “boss” that appears in the game. There is also Hedlok, an enemy that can appear. He has three of one type of ARMS on each side of his body, for a total of six. There’ll be a new way to face Hedlok after the ARMS July 12, 2017 update. That is in a new versus mode.
The ARMS Hedlok mode was revealed in an interview Eurogamer conducted with Kosuke Yabuki, ARMS’ Producer. In this new two to three player mode, available online and offline, people fight over the Hedlok mask. Once donned, they become Hedlok.
ARMS is available for the Nintendo Switch. The July 12, 2017 update adds Max Brass, the Hedlok mode, and a number of balance updates.
