Icarus is a multiplayer survival game that uses mission-based sessions. These are called leads which give the player a certain amount of time to complete their mission and return to orbit. On the surface, players can explore, gather resources, and build a base. But you might be wondering if your base remains after completing the missions.
After completing a mission, any base or anything else you left on the planet is destroyed. This means you cannot return to the planet and pick up where you left off. Each time you return to the planet for another mission, you must start over.

The exception to this is outpost mode. In this mode, players can enter and exit as they wish and any structures they build will remain. Players cannot complete missions or gain experience in this mode. They also cannot transfer anything from outpost mode into the main game mode.
On shorter missions, it is better to build small shelters or use caves as bases. Building a large base is pointless unless you have plenty of time, so think carefully before you start building.
