Structures

**Structures** are obstacles that the player must face during a run. Most have a chance to give technologies when destroyed.

### Green planet

#### Rocks (0-800m)

**Rocks** are found all throughout the green planet. They appear sporadically in place of regular blocks, dealing a bit of block damage on contact. As the player mines deeper, rocks will grow larger in size and deal more damage. Each layer has its own rock type, getting more damaging as you go deeper. Rocks also start spawning in rows starting at 300m.
Unlike other structures, rocks cannot give technologies.

#### Bug nests (100-800m)

**Bug nests** are structures that spawn starting at 100m. They spawn bugs that chase after the player, aiming to kamikaze onto the miner to have adverse effects. There are different types of nests and bugs:

##### Standard nests (100-500m)

Standard bug nests have green spots. They spawn regular bugs that deal damage to the player on contact.

###### Blinders (200-500m)

Starting at 200m, standard bug nests will alternate between deploying regular bugs that deal damage and blinders that deal no damage but severely reduce the player's vision. Blinders can be distinguished by the spines on their backs.

##### Thermal nests (500-800m)

Starting at 500m, all nests will become thermal, indicated by the orange spots instead of the usual green. These deploy thermal bugs that deal thermal damage on contact but that are otherwise identical. Thermal nests also alternate between thermal bugs and blinders.

#### Thermal mines (200-800m)

**Thermal mines** are structures that detect when the miner is close and begin detonation. If a mine is not destroyed in time, it will explode, dealing massive thermal damage to the miner. The damage taken falls off with distance.

#### Laser turrets (300-800m)

**Laser turrets** are structures that spawn starting at 300m. There are multiple types, but all shoot a continuous laser beam with limited range and rotate around to target the miner.
**Standard** laser turrets (300-800m) have red lasers that deal rapid damage on contact.
**Energy-sapping** laser turrets (500-800m) have blue lasers that drain energy on contact.
**Thermal** laser turrets (700-800m) have orange lasers that deal thermal damage on contact.

#### The Queen (700-800m)

**The Queen** is an enemy that spawns starting at 700m. She remains close ahead of the player no matter how fast or slow the miner moves. The Queen periodically shoots triplets of bugs at the player in an attempt to destroy the miner. One bug out of every triplet will be thermal.
Since the bugs are nearly impossible to dodge unless the player is using a maxed H3 Wasp, it is best to invest in durability. Do note, however, that the Queen cannot follow the miner into the core, and the bugs she shoots will vaporize on contact with plasma rock. Once the player jumps to the red planet, she disappears for good in that save file.

### Red planet

The red planet has no new structures, instead borrowing powerful ones from the green planet:

* Rocks like those found at 700m on green
* Thermal nests
* Energy-sapping and thermal laser turrets

All of these function identically on the red planet compared to the green planet.
