Diablo 4 is an ARPG MMO from Blizzard Activision. This game is the next chapter for Diablo and Blizzard fans, and it is absolutely massive. The world is open, consisting of a huge map with tons of side quests, dungeons, world bosses, materials to collect, and more. There's so much to do and so much to see that players will most likely want some help while exploring the world of Sanctuary.
