Evaluation

Legacy of Dorn: Herald of Oblivion is a digital adaptation of a published gamebook — it launched on December 2, 2015 as a complete, self-contained product with no post-launch content cycle. The game was removed from Steam in June 2020 when Tin Man Games' Warhammer license was not renewed. On April 14, 2026, it returned to Steam as part of the official "Warhammer Classics" event — a curated collection celebrating historic Warhammer titles. The store description explicitly frames it as a classic, noting that "some of the content may not accurately reflect current depictions, lore, or presentation within the current Warhammer universes and settings." This framing confirms it is being preserved and re-released as-is, not actively developed or updated. There is no indication of any new content, updates, or future development plans. The game is complete as originally shipped.

Evidence

Game re-released on Steam as part of the Warhammer Classics event after nearly six years of being delisted. No new content mentioned — framed as a return of a beloved classic.

About this game

A vast choice-based digital gamebook set within the Warhammer 40,000 universe where you are a Space Marine!

You are a veteran Space Marine of the Imperial Fists Chapter. Equipped with powerful Terminator armour and armed with the deadliest weapons that the Adeptus Astartes wield, you are a symbol of the Emperor's might. Trapped aboard the space hulk Herald of Oblivion and the only survivor of your squad, you must fight your way through the aliens and heretics that infest the star vessel and find a way to escape the horror and return to your Chapter.

Herald of Oblivion is adapted from the gamebook written by Jonathan Green and was originally published by Black Library/Games Workshop.
