Meteor Dungeon

The Meteor Dungeon is a very rare dungeon that can generate in your world.

Generation
It can generate in any biome. The dungeon itself won’t be visible, but it will generate a small pillar that can be mistaken for a charred tree. It has a 1 in 15000 chance of generating in a chunk, this value can be changed in the config.

The pillar is 4 blocks tall, it's black and has the Lambda logo (λ) on top.

Dangers and Possible Strategy
The dungeon can be classified as possibly the most dangerous structure in the mod. Aside from the very low light level that spawns vanilla mobs, as well as cyber crab assemblers, which should be destroyed first when preparing an expedition. Before attempting to enter manually, make sure you are eqipped with enough kinetic weapons and ammunition. (at least a rifle, although a minigun would be preferrable) If possible, a gassing operation can be attempted, where the tunnels are filled with poisonous gas to kill most mobs. The remaining mobs should be cleared manually. Do not use nuclear or explosive weapons in the vicinity of the dungeon, as it could damage rooms, and cause a leak of contaminants (notably balefire).
