War raged for over a hundred years until strong, powerful Lords emerged from the fighting to bring a fragile peace to the land. This peace is threatened when one of the Lords, Ataraxis, ruler of the city of Nexus, is taken ill by a deadly curse. A call is sent out, promising rewards beyond measure for anyone who finds a cure. Four mercenaries, each with their own strengths, weaknesses and motivations answer the call. One uses forbidden spells to rain death on her foes, one has guns and bombs to blast his way through, another has a mighty sword capable of slicing through entire packs of enemies, and one other gains strength from savagely tearing through anything that stands in his way with brutal, bladed fists.
Heroes of Ruin is a dungeon exploration based action role-playing game. The player can build a character based on a series of classes with various techniques ranging from close to long-range combat, as well as offensive and defensive magic abilities. Players can take quests from NPCs in Nexus and venture into the world to complete them. If the player so wishes, they can be joined by up to three other players, either locally or online. They can either join another player's game at random or set up their own game to complete story quests in co-operative mode. Players can communicate with other online players using voice chat. There are also daily challenges downloadable from the internet for the player to undertake.
