Gateway Event is a special event dedicated for expedition. Exploring the Gateway offers you the best probability of getting useful rewards like Free research, officiers, biome bonus to planet, dark matter, resources, and others. Each event has the same probability to be triggered, that means, getting resources has the same probability as winning free research.
Spamming Gateway Expeditions into the same coordinates reduces the chance of successful findings and players can send a maximum of 3 recurring explorations.
The more certain Gateway is explored, longer will be the exploration mission time.
The coordinates can be shared between players.
