Dungeon Runners

Dungeon Runners is a free-to-play hack & slash style massively multiplayer online role-playing game. There is no overland movement here - the player is instantly taken into the randomly generated dungeons populated by hostile creatures he must slay.

Fighting as a warrior, mage or ranger, the player has access to a variety of skills. Various abilities can be combined as well. The game has humorous overtones: for example, the player character can arm himself with cardboard tubes and wear paper machet armor, and the most powerful mythic items are called rainbows. A subscription of $5 per month unlocks various benefits for the player, although this is optional.  The game also sports humorous in-game ads.
