Evaluation
Unseen Diplomacy is a short VR experience that was originally created in about a month for a 2015 gaming event (GameCity 2015) and released on Steam in April 2016 due to popular demand. The developer has always been transparent that this is a roughly 4-minute experience — not a full game — and the store description still reflects that original scope.
In June and October 2016, the developer expressed hopes for expanding the game with new rooms and content, but acknowledged they were a two-person team working after hours with limited funding. No new rooms or substantial content updates were ever delivered to the original game.
In November 2018, the developer teased a sequel, Unseen Diplomacy 2. Then, on May 27, 2025, the sequel was formally revealed with its own Steam store page, with the developer noting they spent six years developing it into a full title. This sequel announcement makes clear that the original game's development concluded long ago — the energy went into building a proper follow-up rather than expanding the original.
The original Unseen Diplomacy shipped as a finished (if small) product and has received no content additions since its April 2016 launch. Development of the original is complete.
Evidence
Unseen Diplomacy 2 formally revealed on Steam after six years of development, described as a full game built on the original jam experience. Confirms the original game has been complete for years while the team worked on its successor.
Store description explicitly states the game is 'a 4 minute experience, created in a month and designed for GameCity 2015, and now released on Steam due to popular demand' — making clear this is a self-contained, scope-limited release.

About this game
About
Unseen Diplomacy casts you as an elite member of The British Espionage Tactical Initiative, defeating the plans of evil-doers around the world.With a real-life obstacle course created by the Vive’s incredible virtual reality environment, you will run and roll, sneak and solve your way through volcano lairs and moon bases.
It behaves like ‘redirected walking’, which means the core control of the game is directed by the player's own movements.
The experience is focused through clever use of room layouts - by warping and manipulating space without you being aware of it, Unseen Diplomacy allows you to explore and navigate your way through a much bigger environment - no teleporting or portals required!
Virtual reality is a unique experience and Unseen Diplomacy is an intense and immersive game designed to offer you a glimpse into espionage life through your own eyes and movements.
Unseen Diplomacy has received strong attention and interest so we’re really pleased to be able to bring it to Steam in this format. This does mean that it is very much an experiential game - see below for guidelines on how to make the most of Unseen Diplomacy…
IMPORTANT
- Unseen Diplomacy is a 4 minute experience, created in a month and designed for GameCity 2015, and now released on Steam due to popular demand.
- The game *requires* a full 4m x 3m tracked space with no physical obstructions. If your setup does not meet these requirements you will not be able to play.
- This is a single player version of the game, with a social screen so people can view what's happening inside the kit.
- This game requires physical activity! There is an option to allow for users with limited movement to play. We suggest that users have to be able to move themselves around the space (be it wheelchair or otherwise), for the safety of anyone in the room and themselves.
If you don’t feel like your space meets the requirements, head to the National Videogame Arcade in Nottingham, UK, where you can play the game in their VR exhibition!
