Empyrion: Galactic Survival Wiki

Water is one of the most important terrain features in Empyrion: Galactic Survival. It is found in small puddles, ponds, lakes, oceans, within ice, and certain types of soil.


Drowning alert

Water in Empyrion: Galactic Survival currently does not flow, and behaves as a semi-transparent block with no hitbox. Players can see the world around them with a blue/green hue (depending on the type of water). Players can swim in or under water if they do not have any weapon or tool in their hands. If they have a tool or a weapon in their hands, players will walk on the floor underwater. Players start to drown immediately if they go underwater without a helmet on. Drowning adds a red hue to the display and shows the alert "You have no oxygen to breathe" at top right corner of the HUD.

It is impossible to shoot a weapon underwater but it is possible to use tools. Drones and alien base turrets will fire on submerged players should the player be within line of site and range. Other mobs can see players, but don't go into the water, making it a safe retreat location when chased by non-Drone mobs.

Particle effects of splashing water can be seen if any vessel flies/hovers close to the water.

Various kinds of water sources have various types of quality which determine how much time it take to produce one unit of resources in various resource generator.
