Dungeon Fighter Online is hosting a new event, and since you're hearing about it here, it's an event related to fighting games! Fighting games from SNK, to be more specific.
If you haven't heard about it before, Dungeon Fighter Online is a 2D MMO Action RPG that has an audience of nearly one billion players. Though immensely popular, it's not quite as well known outside of Asia, though it definitely got more eyes on it thanks to DNF Duel.
For this event, you will be able to join in for either PvE or PvP mode, with both offering you to play as some of the classic SNK characters. As you complete missions, you will be able to earn a bunch of SNK themed rewards, including a little super deformed Haohmaru creature.
For anything more, you'll have to check out the store.
