In the wonderful world of HellMOO there are strange powers gained through the wonderful effects of radiation. These powers are called mutations and there are many mutations available in the game. Their locations are documented in Injection Junction in Freedom City (marked IJ on your map). The mutations can be acquired in specific locations that are hidden or a little difficult to reach. When you find a mutation, something similar to this will appear:
You realize you could mutate here. Type 'mutate snakeskin' to develop the 'snakeskin' mutation.
Will you mutate?
If no, then just continue with what you are doing. If you don't type the exact command, you will not gain this mutation. If yes, then something will happen, very similar to this next example.
[ Your slashing resistance increased by 2 - 4! ] [ Your stabbing resistance increased by 1 - 3! ] Creature's body twists and shudders... [ You've developed the 'snakeskin' mutation! ]
Before you mutate, think it over. Removing mutations is costly. So, make each choice wisely. Some mutations are considered superior to others due to their gameplay benefits, those will not be singled out here. Your mutations are a part of what makes your character unique. It is up to you to decide which mutations make the most sense for your character. Mutations can be pretty useful but they also have their downsides.
Generally, if not always, mutation areas are slightly irradiated. Radiation comes with its own dangers, such as special temporary radiation mutations or cancer (which is not a mutation). However, gaining radiation mutations from mutation areas is difficult - your rad count will generally drop faster than it will increase. As such, highly irradiated areas (like the Wasteland) are your best shot for gaining a radiation mutation.
Note: The soak/focus/other distinction does not exist in-game, and is merely for convenience.
Soak mutations (or "Skin mutations") are now limited to three per player. Level 2 mutations are all upgrades to level 1 mutations and require their level 1 counterpart. You can have 3 soak mutations in total.

|Blink|| Gives you the ability to
to a random place using focus. If your focus is high enough, you can also successfully for precise transportation.|
The higher your focus, the lower the chance of blinking to an undesired location. Regardless of that, you will always have the risk of telefragging (blinking into a tile with someone else in it, causing you to explode). It has an interesting effect when combined with Hooligan.
|Labyrinth Necropolis' Heart|
|Flight|| Gives you the ability to Focus builds that will neither go Blink nor Medium.
, , and - imagine a faster jetpack that doesn't blow up. This makes it a neat choice for low |
The downsides are that the skies are really damn cold and full of Chupacabras.

Incompatible with: hideous freak, chud, vampire, and zombie
|Chud|| Gives +1 senses, +1 fuck, +2 climb, -2 pistols, -2 rifles, minor beat, stab and slash soaks and some new commands:
to wail to other chuds within an area, or if no text is supplied, to wail for minions; and to show information about your current minions and reputation. A higher tier of reputation means better minions for you.
One of the less popular racials as minions are lackluster, the buffs are weak and sunlight stress is annoying.
Incompatible with: hideous freak, vampire, chromemouth and zombie.
|Empath|| Gives +1 brains, +2 senses, +3 focus, and +2 medic, +3 to Medium's

|Vampire|| Turns you into a permanent vampire. +4 to brawn, cool, endurance, and senses. -4 to brains, plus night vision.

While the buff numbers are really great: Vampire hunters are a pain in the dong, you essentially won't be able to play half the time and have to micromanage your hunger level. Advanced players only.

|Billygoat|| Can eat almost anything you can carry - including whole fridges, couches and TVs. This will heal you a bit every heartbeat. Chance to barf up components from eaten items.

Incompatible with: zombie.

+3 to brawn, -1 to endurance, and +1 to wrestle because you are stronk.

|Enigma|| You are a complete mystery to others. People can't accurately determine how strong you are, what ailments you suffer from, or how to fix your mental afflictions.

Gives +2 cool, -1 senses, you cannot be diagnosed, analyzed, or appraised by anyone, including yourself.
|Back room of Heaven bar in Gangland.|
|Fibrocartilage|| +5 Max health, +95 resistance to all anti-aging methods.
Additionally, endocrine boosters will be a little more likely to work.
|Hooligan|| Something's...not right with your head. You have trouble focusing, and you're prone to bouts of brain damage. On the plus side, this makes it difficult to stun or distract you. It has a 'bonus' when combined with the Blink mutation.
Gives -3 focus, +35 stun resistance, +1 Wrestle. You get a Brawn and the weight of your head armor. Hit chance is wrestle versus dodge.command, with damage based on
|Nukem Academy - 2nd Floor|

+1 Scavenge, -1 Cool, +1 Senses. Gives thecommand which tells you one item that can be scavenged in the room (including stashed/hidden items), and the command, which will attempt to display the number of the specified item in the room, including in containers and in the inventory of other players.

+1 medic, +1 scavenge, +1 locksmith. Always see the @nudes of other players by looking at them.: Peer into closed objects or other peoples inventory.
These mutations can only be gained from reaching a certain amount of rads - you need around eight rads to gain a radiation mutation, and you can have more than one. These mutations are temporary; when you die you'll lose them. If you have high endurance you may shrug off getting the mutation. If you're specifically trying to get one of these mutations, the easiest way is to sit in a room with a few spent fuel rods until sufficiently irradiated. Failing that, you can wander around in an irradiated area such as the wasteland or the glass mesa, but both of these are more dangerous.

To acquire a mutation you require a free mutation slot (radiation mutations are exempt from this). You begin with one free slot. To gain additional mutation slots, you must acquire a set amount of XP (note however, that this looks at total acquired XP, not XP available for use). Your first two additional slots come at 4,000 XP intervals, then a third at 5000 additional XP, and a fourth 7000 additional XP. After this, 10,000 additional XP is required. There is no cap to the number of open slots you can have.
[You earned another mutation slot!]
It's possible to remove your mutations now through a device on Stormfront Island. However, there are penalties that come with this: You age 10 years. Your health drops to 25. You lose 1 raw from a random skill from your top three. You lose $50,000. The Purity mutation cannot be removed in this way.
The following is a list of mutations that are no longer available.
|Mutation||Effect||Reason for Removal|
|Jammer||Nullified all focus mutations used in the same square. -10 focus||Negated by other changes|
