Endless Dungeon has made a name for itself with its mix of horde survival and tower defense mechanics. Similar to many other roguelites‚ a large part of the game is about preserving your resources for the final boss fight. Each run into the Core in Endless Dungeon will get more difficult‚ and at times‚ it can feel almost impossible. If you're not prepared for it‚ it's very easy to run out of resources when you need it‚ or find yourself hopelessly outmatched against oncoming waves of monsters because your characters are too weak.
