Advanced Dungeons & Dragons: Treasure of Tarmin

Advanced Dungeons & Dragons: Treasure of Tarmin is a video game for the Intellivision video game console and the Mattel Aquarius computer system. This game was a licensed Dungeons & Dragons adaptation. It is a successor game to Advanced Dungeons & Dragons: Cloudy Mountain (1982).

Each enemy (aside from the Minotaur) can be found in three colors, signifying different levels of difficulty. Skeletons: The weakest enemy in the game. They attack the player's War health and are very easy to defeat. Cloaked skeletons are more difficult to defeat. Both regular and cloaked skeletons may have shields, which increase their difficulty. Giants: The other primary enemy to attack only the player's War health. These can have shields as well and are more difficult than Skeletons. Giant Ants: The weakest of the enemies who attack the player's Spiritual health. Dwarfs: Much like Giants in their difficulty as well as attack. Giants come either with or without shields, but attack only the player's Spiritual health. Giant Scorpions: Mid level enemies who attack the player's Spiritual health. Giant Snakes: Giant Snakes attack the player's Spiritual health and have more health than Giant Scorpions. Alligators: The next more difficult of the Spiritual attacking enemies. They do a great deal of damage. Dragons: The most difficult of the Spiritual enemies. Ghouls: These do not appear in the game until the player has gone several levels down. They may attack either the player's War or Spiritual health during the battle. On the easier two game difficulties, its type of attack is determined randomly, but on the harder two difficulties it attacks the weaker health. Wraiths: These are more difficult than Ghouls and can be either shielded or normal. Deeper into the dungeon, Wraiths can become harder to defeat than the Minotaur itself. Minotaur: This is the "end boss" of the game, and it only appears in one color (purple). It attacks both Spiritual and War health. Upon defeating the Minotaur, it will drop the Treasure of Tarmin; the Treasure can be picked up to end the game or ignored to continue playing. Additional Minotaurs show up on lower levels and often even in the same level. "Door Monsters": These special creatures look like doors and hide the three spellbooks. Blue (the weakest) gives a book that teleports through walls. Pink gives a book that allows vision through walls. Purple tends to strike with high end Spirit weapons and gives a book that turns ordinary items to platinum (thus making any war weapon or treasure the highest value possible). Bombs: Some treasure chests and bags contain small or large bombs that explode to cause war damage.

To increase health, the player must either attack or be attacked by enemies, followed by resting (consuming a food item), which has a chance to increase either war or spiritual health based on the weapons the player has used. With the aid of Spirit or War tomes found in treasure chests, this chance may be increased greatly. The player's maximum health (with the aid of maximum health limit increasing books and potions) is 199 War points and 99 Spiritual. In the outer hallways, gates between adjacent mazes on the same level may be encountered. Passing through a green gate reduces the player's spiritual health and boosts the player's health, and the opposite effect occurs passing through a blue gate. Use in conjunction with war or spiritual books can boost respective health significantly. Passing through a tan gate changes nothing. The player may keep going down levels (by accessing a ladder located inside each maze) until level 256, after which the game cycles the player back to level 1, with the player's character retaining their inventory and health, but attacking enemies at the first floor's easier difficulty. It is possible to be defeated but not lose the game. Upon dying, the player can be 'reincarnated' to another section of that maze, with all of their pack's inventory gone while retaining the contents of their weapon and shield slots as well as their supply of arrows and food.

The game was written by Tom Loughry in 1981 and was published by Mattel in 1983. Treasure of Tarmin was the second AD&D game for the Intellivision, after Advanced Dungeons & Dragons: Cloudy Mountain. A version was also released for the Mattel Aquarius home computer. In 1983, Mattel Electronics commissioned an Atari 2600 version of Treasure of Tarmin. This was developed by Synth Corporation in Chicago. Two Synth software developers, Michael Bengtson and Neal Reynolds, wrote the game to conform to the play of the Intellivision version. While the game was completed, it was not released before Mattel Electronics closed their doors.

German gaming magazine TeleMatch gave the game a very positive review, giving it a one and a half out of six, (on their rating system one is the highest), stating, "Advanced Dungeons & Dragons is already the outstanding pinnacle of Intellivision Cassettes, but Treasure of Tarmin raises the bar even further" and, "at least for the German market, no other video game of this type exists What happens next is almost unbelievable: you yourself are the adventurer, and you're not represented by a symbol of a small man on the screen, rather you see what one would see if one was walking". TeleMatch was also very impressed by the number of levels in the game, and felt that the awarding of points for defeating monsters was rewarding. In a retrospective review of Treasure of Tarmin in Black Gate, Ty Johnston said "this is a game worth playing, loaded with thrills and fun".
