Arcterra is a cold planet, being completely frozen over as it is the farthest planet from the Alimbic sun. Because of the extreme cold, it is populated mostly by machines, such as Voldrums, Psycho Bits, and Guardians, as well as the odd Alimbic Turret.

The outermost planet in the ALIMBIC CLUSTER, ARCTERRA is an inhospitable wasteland noteworthy for a honeycomb of tunnels and caves within its frozen interior.
Arcterra (The Ice Cave)
"This planet is located at the farthest reaches of the Tetra Galaxy. Arcterra is a barren and frozen world with caves and underground catacombs."
Arcterra is a portmanteau of "terra", which is Latin for Earth or land, and "Arc", which is Latin for cold.
The word Arctic comes from the Greek αρκτικός (arktikos), "near the Bear, arctic, northern" and that from the word άρκτος (arktos), which means bear. The name refers to the constellation Ursa Major, the "Great Bear".
- The second area of Arcterra's music is a remixed version of the Phendrana Drifts' main theme.
- Noxus and Trace are encountered for the first time here.
- Like Alinos, during the first visit on Arcterra, one of the hunters is encountered on the way to the first Octolith while the other is encountered during the escape.
- In multiplayer, when selecting the map, Fault Line is featured twice, one with just the Fault Line arena, and the other featuring Fault Line with a shortcut to Subterranean. However, the two arenas' names are incorrectly switched.
