One of the games that Paradox Interactive brought with them to the 2012 Game Developers Conference was Dungeonland.
Dungeonland mashes up dungeon crawling and theme park adventures into the same theme. The heroes are trapped in a fantasy theme park that is hell-bent on killing them. There are three classes; the Rogue, the Warrior and the Mage.
The heroes adventure in a classic co-op dungeon crawl fashion with a twist. The mulitplayer action allows for three players to be the heroes with a fourth taking on the role of Dungeonland’s Game Master. The GM can use various traps and monsters to kill the park visitors.
There isn’t a release date at this time but Dungeonland will be on PC.
