Katalund is a high level “planet” dungeon introduced for Month of the Mad God 2019. Like the rest of its kind, it is a timed gauntlet dungeon where players race against the clock to dispatch waves of enemies for loot.

This dungeon is a source of various stat increase potions and various pieces of alien gear.

Wormholes to Katalund spawn randomly when the Alien UFO event boss is slain.

This dungeon must be completed to earn ‘Far Out‘, ‘Season’s Beatins’ and ‘Realm of the Mad Godfame bonuses.

The Realm Eye says:
Katalund is a vast desert planet swallowed in its own toxic clouds. Only inorganic lifeforms make their home on its surface, rebuilding themselves from the scrap of an ancient civilization.
Commander Calbrik aims to build a mobile military base that would move within the pockets of breathable air, virtually unassailable thanks to the planet’s natural defense.


Katalund Key The Katalund Key is not sold directly in the Nexus, although it has appeared in certain Mystery Boxes and Packages before.


Layout and Mechanics

Katalund consists of a roughly square-shaped area, with the enemies spawning from 4 UFOs along the edges. Like the Ocean Trench and Cnidarian Reef, there is an oxygen meter in play - the majority of Katalund is covered in a moving cloud which drains oxygen when stood in. There will always be a cloudless “strip” somewhere in the dungeon, which sweeps horizontally across the arena before moving back to the opposite side.

It is important to note that all of the enemies will be Armored as long as they remain in the gas cloud. The only exception to this is the Golden Sphinx, which is Invulnerable instead.

The Dungeon is a timed gauntlet: players are tasked with killing waves of enemies as fast as they can, with the Alien Satellite in the center giving warnings to how much time is left. Every time the stage is cleared of enemies, more will spawn in to replace them. There are three waves with 4 sub-waves each - for a total of 12 waves - and every fourth wave has a designated boss that can drop loot.

If the time limit runs out, the enemies will stop spawning after the current wave is defeated, with the Alien Satellite turning into a wormhole back to the Realm. On the other hand, if all 12 waves are completed within the time limit, the Satellite Core will become vulnerable and can be destroyed for extra loot.

As players advance through the waves, the difficulty of the enemies will increase:

  • Waves 1-3 feature Nano Silver Walkers, Nano Steel Reapers, Steel Reapers, and Iron Titans. The Neo Iron Titan appears as the boss of wave 4.
  • Waves 5-7 add Silver Walkers, Nano Platinum Stingers, and Neo Iron Titans. The Neo Silver Walker appears as the boss of wave 8.
  • Waves 9-11 add Giga Steel Reapers, Platinum Stingers, and Neo Silver Walkers. The Golden Sphinx appears as the final boss in wave 12.

In addition, the amount of time alotted for each wave increases along with the difficulty. However, the amount of time alotted also decreases with the number of players in the dungeon.

Note: After a boss is killed for the first time, they can appear in any following waves as standard enemies. They can still drop their loot, albeit without tokens. Like the other three wormholes, the first two bosses are stronger versions of normal enemies, while the final boss has an original design.
