The Grineer Forest (also named Earth Forests) is the 9th Tileset to be released, after the Corpus Gas City. Found on Earth, these dense jungles are populated with plants genetically engineered by the Orokin to be extra resilient and immune to Infestation. Attempts at colonizing the planet by the Grineer have been repeatedly thwarted by the vegetation, resulting in the various overgrown Grineer structures that can be found during exploration.
Similar to Mars, Grineer units here are variants known as Frontier units, equipped with the Karak and forest camo. Wild fauna are also present in the form of Feral Kubrow, dog-like creatures that will attack anything that gets too close to their burrows.
During the Sabotage mission on this tileset (on the Cervantes node of Earth), 1 of 6 different antitoxins can be brought with you on the mission to earn a bonus reward. The difference between each antitoxin or the number of antitoxins used (up to 4) has not yet been determined, but it likely increases the drop chance of rare items.
Each player may bring a single antitoxin with them. You are not allowed to equip more than one type of antitoxin at a time.
This hazard is only found in defense missions, it appears as a form of exhaust on an industrial chimney. Climbing up to the chimney may damage your Warframe. This also affects Zephyr's Tail Wind when she launches to the sky too high. Oddly enough, Slash may sometimes be procced despite the lack of presence of physical hazards.
They appear as a wild faction, and will attack both Grineer and Tenno alike. Although they present little threat, Kubrows can sometimes disorient Tenno from their action by biting their leg, pulling them in vain.

- This tileset is the first to have a day-night cycle.
- As of Update 12.0, this tileset now switches between day and night every 4 hours – as opposed to every 6 hours pre-update 12.
- For reference, the tileset turns to Daylight on server daily reset which occurs at 12:00 AM (midnight) UTC.
- Insect and/or animal sounds can be heard while in this tileset.
- Stealth is more viable in this tileset since there are no alarms.
- When a player is near the pad that is used for extraction, Grineer dropships can be seen flying by.
- If the host leaves, forcing a host migration, the map may switch to night despite it previously being day, and vice versa.
- In seemingly random missions, the framerate can sporadically stop-and-go. This can lead to more unpleasant effects such as ambient sounds playing to painfully loud levels, and in rare cases, causing the client to become unresponsive and crash. (Cause unknown)
