Dungeon Defenders

Dungeon Defenders is a multiplayer video game developed and published by Trendy Entertainment that combines the genres of tower defense, RPG, and high fantasy/action/adventure/strategy where one to four players work together to protect one or more Eternia Crystals from being destroyed by waves of enemies which include goblins, orcs, kobolds, ogres, and wyverns. The game features a number of levels, consisting of around five total waves, through its campaign mode, or other levels as part of challenges; some of these levels may feature a final wave that includes a boss battle against a unique foe. The player characters defend crystals by either magically creating, maintaining, and upgrading towers or other defensive elements that damage or divert the enemy monsters, or by using melee and ranged attacks to defeat enemies directly. If an Eternia Crystal has taken too much damage, it will be destroyed and the players will lose that level. Successfully defending a wave will earn the characters experience points based on the difficulty plus additional bonuses, namely preventing any damage to the crystals, preventing damage to your character, and only using weapons to kill monsters; successfully completing all waves of a level will earn the players a large banked mana boost. Monsters will also drop items that can be sold for additional banked mana.
