In the posters, Zeronus is portrayed as a tourist world like Gyre, but on the posters it says:
- 'Guaranteed Alien Free'
- 'The only planet with extra oxygen for a real relaxed vacation'
- 'Sun 24 hours a day'
On the poster is a background of the planet's surface which appears to be covered in large, beautiful beaches and jungles; separating the beaches and the jungles are cliffs, making Zeronus a large tourist destination. The quote of 24 hours of sunlight implies that Zeronus is either a gimmick or the colony is a moon in locked orbit around a gas giant.
