Spec X 2026 registration
You can showcase the worldbuilding of your book, seed world, videogame, or anything as long as it sticks to the principles of hard sci-fi, meaning your world and its elements should at least be believable according to real-world science.
Presenters will be given a 15-minute time slot to present their project. After the presentation, there will be a Q&A.
For any queries or updates on your submissions, you can join and ask in the official Discord server.
