Dungeons of Dredmor is a turn-based roguelike that was developed and published by Gaslamp Games, Inc.
The developers currently sell Dungeons of Dredmor for $4.99 for the base game, and $6.99 for the complete collection which includes the two additional DLC packs (which regularly cost $2.99 each). The “You Have To Name The Expansion Pack” is a free bit of DLC that adds in additional items, enemies, rooms, and skills.
Steam Workshop support allows players to further customize their Dungeons of Dremor experience with fan-made mods. One in particular that caught my eye is the Wrestlemancy mod that adds in a skill tree themed after a professional wrestler.
Dungeons of Dredmore was PC Gamer’s US Indie Game of the Year for 2011.
