Realm of the Mad God

Realm of the Mad God is a small and unique MMO featuring a Roguelike, bullet hell, shooter combat, isometric 2D visuals, and hordes of monsters to slay, while also drawing from gameplay elements more common to RPG games, such as classes, builds, dungeons, and more.

It’s most unique mechanic, however, is a Permadeath system in which you lose everything you have on your character upon death. It’s entirely Free-to-Play, but it does have a heavily Pay-to-Win monetization model.
