Kalypso announced its release with a brief presser stating:
It’s time to stop being a goody-goody hero, and start being a sneaky, nasty and vile villain, as Kalypso Media is pleased to announce the release of a free downloadable demo for Dungeons, the game where it pays to be bad! The demo, available at the mirrors below, gives players a taste of what it will be like to be the Dungeon Lord, as they play through three single-player levels, and a survival mode map. Grab the file from any of the links below, and prepare to show those pesky good-guy heroes who the boss is, as you build elaborate dungeons, all crafted with one goal in mind - - to lure in and capture adventurers, so you can steal their soul energy! For more information about Dungeons, please visit the recently launched official web site at http://home.dungeons-game.com.
You can read Strategy Informer's review of the game. You can also try the game out with the newly released English language 510MB demo .
