Dun Darach

One day Cuchulainn travels home with his charioteer companion Lóeg from a battle against the Connachta. On the way, they stop off at an inn and Lóeg is persuaded to help a young woman named Skar, whose chariot is damaged. Cuchulainn realizes that Lóeg is missing after taking refreshment at the inn. He later discovers that Skar is a sorceress and ally of the Connachta, and has taken Lóeg to the Secret City of Dun Darach in retribution for the death of Prince Amhair, who perished in the battle. Cuchulainn goes on a long search for the mysterious city, eventually discovering it and entering to find Lóeg.

Dun Darach is an action-adventure game. The player guides Cuchulainn through Dun Darach and interacts with the environment by performing keyboard commands. The main objective is to find Lóeg, taking side quests from non-player characters (NPCs). These NPCs can give short hints to Cuchulainn, rob him, and confiscate his belongings if he carries stolen goods.

Dun Darach was developed by Greg Follis and Roy Carter, the co-founders of game developer Gargoyle Games, as a prequel to their previous title, Tir Na Nog. It had the working title Cú Chulainn – The Early Years. Development first began on 10 February 1985. Follis claimed that the biggest complaint for Tir Na Nog was its huge setting, resulting in it being scaled back to one city.

Inspiration for Dun Darach came from the works of Fritz Leiber and Michael Moorcock, with Gargoyle wanting the atmosphere to be similar to Leiber's book The Swords of Lankhmar. It was showcased at the LET trade show at the Olympia London, showing screenshots of the game.

The original release of Dun Darach received critical acclaim, particularly for its graphics. The ZX Spectrum version was voted number 57 in the Your Sinclair Official Top 100 Games of All Time. Richard Price for Sinclair User, while describing the game as "less abstract" as Tir Na Nog, said it was more interesting and eventful than its predecessor. Computer And Video Games considered it a worthy successor to the first, calling it "entertaining".

A reviewer for Crash declared it an essential purchase for ZX Spectrum owners and saw it as a contender for game of the year. Retrospective appraisals were less agreeable. Eurogamer contributor Peter Parrish offered an average score overall, dubbing it "mystifying". Ian Marks from Retro Gamer compared it to Tir Na Nog, saying both were fun to play but Dun Darach was not as good.
