Mutations are special abilities in HATEMoo that give stat bonuses and special commands. There are five distinctive types of mutations, soak mutations which grant resistances to elemental and weapon damage, focus mutations which use the focus skill to perform feats with your mind and body, movement mutations that allow you to surpass obstacles and move around easier, class mutations, radiation mutations, and miscellaneous mutations. Most mutations have two "levels".

Please note the distinctions between mutations are not made in game.

Chiller Lets you freeze objects encasing them in a block of ice that preserves consumables indefinitely until the block melts, puke antifreeze vomit on people that "preserves" consumables in their inventory, and freeze enemies which depends on focus, giving them the cold status.

You can attempt to accelerate your orgasm, or orgasm spontaneously, with the Template:Cmd command.

Movement mutations:Edit

These mutations are mutually exclusive with the other mutations of their level. In other words, you can pick Phaser, Clairvoyance, or Leapfrog, plus its respective upgrade, and none of the others. The Leapfrog/Flight path is mutually exclusive with Lithodermis, but now you can have High Density and still fly, making flight somewhat feasible.

Level 1

Mutation Description Location
Phaser +1 focus, gives the ability to Template:Cmd any outdoor spot, and then Template:Cmd to it as long as nobody is watching you or standing in your phase spot. Potential to add focus IP. Wasteland, south east at the very bottom.
Clairvoyance +3 focus, gives you the ability to leave your body and travel around the world, without actually traveling. You are able to see psi shimmers while projected, and if there is too much psi in the room you can take damage. You can Template:Cmd to check for other clairs in the same room, and if you can find them, you can Template:Cmd to damage them. You can also listen to conversations in the room if you pass a focus roll for each time someone says something. The Cave of All Souls
Leapfrog -1 brawn, -1-3 beat resistance, +1 dodge, lets you Template:Cmd up/down stuff. Template:Cmding lets you instantly move in any direction that would normally require a climb. Leapfrog is dependent on Reflexes. Success allows you to instantly move in the chosen direction. Failure causes damage similar to a fall, including the possibility for broken limbs. Increases walking movement speed as well. Mt. Fisty

Level 2

Mutation Description Location
Blink Upgrade to Phaser, gives you the ability to Template:Cmd to a random place using focus. If your focus is high enough, you can also successfully
Template:Cmd for quicker transportation. If you fail the focus, you run the risk of telefragging or blinking to an undesired location. If someone else is in the tile you blink to, you will also telefrag.
The Labrynth (Heart of Necropolis)
Medium Upgrade to Clairvoyance, allows you to Template:Cmd out other players. +1 to focus. The higher your focus, the more accurate the roll. If your focus is high enough, you will accurately pinpoit the area that they currently reside. However, if their focus is high enough, they will be able to either detect that someone is seeking them, detect who is seeking them, or even detect where they are being sought from. Seek your targets with care! Also a great way to get brain damage if your focus is less than around 20. Top of dike (Stormfront Island)
Flight Upgrade to Leapfrog. Gives you the ability to Template:Cmd,Template:Cmd,Template:Cmd, Template:Cmd, and Template:Cmd. The downsides to flight are the cold that affects you while in the air, and the chupacabras which will attack you while flying. Skies above the Necropolis gate

'Class' mutations:Edit

'Class' mutations are the closest things HateMOO has to a class system, they are mutations that dramatically change the playstyle of the game for you if you take them and they should definitely not be picked up on a whim. Usually the class mutation, along with main skill focused on, is the main defining feature of a character. For example, if someone in corpchat asks you what you're building towards, "Clubs Abomination" or "Locksmith/Hack Zombie" will usually tell them what they want to know. Note that taking a class mutation is by no means necessary, and you can build a competent character without any of them if you so choose.

Gives -2 brains, -2 cool, +1 endurance, +1 brawn, +3 fish, -2 firearms, -6 persuade, 4-10 beat, 6-9 slash, 4-10 stab, 8-10 bullet, and 1-4 acid resist, inability to wear regular armor (low thickness limit), can Template:Cmd corpses for healing, Template:Cmd allows you to log out in outdoor type rooms safely, acid jizz/piss, as well as a claws upgrade that gives them radiation damage on top of more damage.

Radiation Mutations Edit

You have a chance to get mutations from having a lot of radiation (The amount appears to be 5 or more). Once you have about the needed amount, simply wait (heal yourself periodically if you need to) and one of these mutations may eventually occur.
