Golden Mix Tournament Xtreme: Arcade Version is a remake of the first game of Rawk Games' Golden Mix Tournament series, which are M.U.G.E.N fullgames (the aforementioned first game share the same title and was originally released around 2016). Xtreme: Arcade Version was released on May 2019 as part of the series' 3rd anniversary, and, like previous entries in the series, features a variety of characters + Hatsune Miku duking it out to stop Orochi (from the King of Fighters) from destroying the world (as described in a separate .txt file that comes with the game).
Golden Mix Tournament Xtreme: Arcade Version doesn't have any common mechanics - each character are made by different people while not following a common theme, and therefore each character functions a bit differently. For example, Hatsune Miku seemingly doesn't have any special moves here, Kyo Kusanagi can charge up super meter by pressing HP + LK, and each character has varying amounts of normal attacks (Miku has only three comprising of light, medium, and heavy attacks, whereas characters like Kazuya Mishima and Ryu have light, medium, and heavy variants of punches and kicks).
