Primulus is a Sci-Fi game that takes place on a research facility on a distant moon. As a player, you are one person working on that research facility. Your job can be anything from cleaning the floors and toilets as a janitor, to exploring the surface of the planet and capturing the wildlife for the researchers and geneticists to analyze. The people of the facility benefit from working together and further advance the facility when everyone is properly doing their job. However, be careful with who you trust though. People aren't always what they seem.
Primulus is a game that takes place in rounds. That is, a game round starts and each player spawns in a specified area of the facility depending on their job. The round ends when the escape shuttle departs from the facility. Each round of Primulus is, basically, a bad day on the job.
