Just as expected, Nintendo has released the 4.0 update for ARMS today. The update is so big that Nintendo has released a brand new trailer for it. However, Nintendo has not released any patch notes that tell us what, exactly, changed. The only thing Nintendo has said on the update’s contents comes from the trailer’s description on YouTube, where Nintendo says that the update adds “a new fighter (Misango), Stage and ARMS”. As for the trailer itself, we’ve included it for you down below.
