Grotesque Tactics: Evil Heroes is a story-driven, satirical role-playing game with a strategic combat system. It is a combination of Western and Asian Strategy RPGs, such as Final Fantasy Tactics, Heroes of Might & Magic, and Fire Emblem. The game takes place in a grotesque world filled with humor and amusing dialogue that pokes fun at some of the most successful RPGs, such as Oblivion, Gothic, and Lord of the Rings.

The game revolves around a party of 10 anti-heroes fighting against the merciless cult "The Dark Church," which has murdered all of the kingdom's heroes and knights. To protect the kingdom, you will have to hire dubious soldiers and rescue jealous maidens who will follow you into combat as your groupies. The game features turn-based tactical battles with humorous animations not seen in any RPG, distinctive party members, gorgeous village landscapes, dark, sinister dungeons, and classical RPG elements like quests, treasures, trade, leveling up, and outfitting a party of unique heroes. Enjoyable multiple-choice dialogues and conversation puzzles in the style of classic adventure games, such as Monkey Island or Maniac Mansion, make it even more engaging.
