The official Street Fighter V Twitter announced today that a new Guts Man costume will be released for the boxing character Balrog next month! This is the second Mega Man related costume added to Street Fighter V following the previously released Air Man costume for the character Rashid.
The costume will be available to unlock in the "Extra Battle" mode starting on February 15th! Hopefully we'll see more Robot Master costumes released for Street Fighter V in the future.
