We're roughly half-way through the current Angband competition with an Unangband save-file. The deepest unique killed so far is Smaug, a level 55 monster. However, the character doing so has just passed away due to an unfortunate spell casting accident, opening up the game to anyone who is able to surpass their efforts.
You can keep following the competition, or submit your own success and/or failure stories to the Unangband ladder. Remember, the point of the competition is participation and challenging yourself. Of course, the glory of submitting a winning entry is quite a nice icing on the cake.
"Don't let the name fool you: The Unnamed Angband has no shortage of distinct flavour that sets it apart from any other variant. You adventure in Tolkien's world, through towns and wilderness and multiple dungeons, journeying from Bree towards greater and greater danger.Welcome to the old Unangband page, a variant of Angband which I developed for over ten years.
This variant roughly doubles the monster list, expands the class-based system of Angband with numerous possible specialties that let you fashion a unique character, offers a positively absurd variety of terrain (cages that trap you, floor chests that can store objects, burnable woods, chasms, bloodstains), and includes a bunch of major interface improvements, including better presentation of graphics and an experimental isometric view." - From angband.oook.cz.
The official Unangband home page is now at at https://dgolddragon28.github.io/Unangband/ which contains links to the latest releases and source code.
I would also like to thank the new Unangband maintainer DGoldDragon28 for taking over this variant. DGoldDragon28 had been developing a variant based on Unangband, and now has my blessing to continue with the main Unangband releases as well.
