Kalypso Media have announced Dungeons 2 for PC, Linux and Mac. The game is set for release in 2015 and is being developed by Realmforge. As with the original it's a game that's inspired by Bullfrog's classic Dungeon Keeper and it will feature a single player campaign with "2 playable factions, 26 unique creatures, multiple types of heroes and game modes" - there's also multiplayer for up to 4 players (4 different modes).
Dungeons 2 will make an appearance at Gamescom next week.
