This month's featured article is ARMS. ARMS is a fairly new Nintendo franchise that debuted with the release of ARMS near the beginning of the Nintendo Switch's life. ARMS is a fighting game that relies on equiping your character with certains "ARMS" to gain the upper hand during fights. The game was also notable for its huge amount of free DLC that kept the game fresh for most of 2017. Recently the franchise has seen representation outside of its own games with the inclusion of Spring Man as an Assist Trophy in Super Smash Bros. Ultimate and of Ribbon Girl as a Mii costume in the same game.
