Earth has been long abandoned due to its toxic atmosphere. It is now overgrown with mutated jungle structures that have devoured most of the prior signs of civilization. Infestation and roaming wildlife still inhabit its surface but anything of value was stripped by scavengers generations ago.
Earth is a planet under Grineer control, and is the first planet players can access. It is linked through junctions to Mars and Venus. Lua, the Earth's moon, becomes accessible from Earth (without a junction) after players complete the quest The Second Dream.
Earth is the only planet to feature the Grineer ForestTileset. Every four hours, the forest tileset will change from day to night, mimicking the day cycles in real life. The change will feature different vegetation that can be scanned for extracts that are used to craft Antitoxins, with Sunlight variants during the day and Moonlight variants at night.
