[//]: # (code/datums/mutations/_mutations.dm for old mutations) ## Tumor types [//]: # (icon file for the tumors is in icons/mob/genetics/tumors.dmi) ### The head tumor ![](https://i.imgur.com/iFUFDVp.png) It's an extra head that grew on you. It has a vestigial brain.... though it could be more than that. Doesn't have its own eyes, but if a ghost takes over it it can look through yours. ### The sacs Small, medium and big. Mainly for harboring things like extra eyes, extra armor, whatever. Usually just fucks your body up, though. ![](https://i.imgur.com/VVGRSzH.png) ![](https://i.imgur.com/dR9v4kl.png) ![](https://i.imgur.com/B3Twiaw.png) ### Puffer Spray chems on people. If it's powerful enough, it could even hypospray inject stuff into people one tile away from you (especially if you're grabbing or aggressive grabbing them). Perfect if you want to modify the genetic material of your victims so they can serve you as thralls, or maybe you've got some romerol... ![](https://i.imgur.com/a1FUr54.png) ### Armsac Grab, punch, give it to a ghost. Armsacs are the basic building blocks for TRUE body horror. You can use them for locomotion, to grab more things, or maybe just to flail around, hitting whatever's closest (including you) ![](https://i.imgur.com/9uAF2ch.png) ### Nosesac Truly inspirational, the nosesac allows you to breathe in extra gases, increasing your lung's efficiency or storing them in gaseous versions of sac tumors for later use. ![](https://i.imgur.com/blWWlud.png) ### Organ tumors Not currently pictured - they reside on the inside, and are much stronger at metabolizing chemicals than external tumors. They can also hold gases, act as chemical containers, or even extra hearts, livers, lungs etc. ## Genes and Genetic Frames [//]: # (all gene_frames have an epigenetic strength and a list of composed gene frames; gene frame composition has different meaning based on what gene you're composing on what. Gene frame implementations define can_compose_with, a proc that tells you if the parameter gene frame can be composed onto the src frame) The building block of your thesis against nature. ### Genes Genes are composed of target, conditional and protein frames. They also have an epigenetic strength that determines how strongly they express ### Target frames [//]: # (internally, gene_frame/target have a list of pairs of organ slots and their influence strength - only for affected organs slots) The way you ensure your acid-creating-protein doesn't rot your brain from the inside. ### Conditional Frames [//]: # (Internally, you get three procs to play with; one shuts down something entirely - might be it's an ability controlled from somewhere else, or it just has a threshhold where it goes from 0 to 100 suddenly. The second - only used when the first one gives TRUE - gives you the strength, which affects protein growth_act growth_strength. The third allows you to register signals; of course, there is a fourth that lets you unregister, but surely you won't forget about that, right?) Control your tumors - make them express themselves and grow only when you want them to. Maybe it's environmental factors, or maybe it's hormones or even a toggleable ability if connected to your brain via neural protein frames. ### Protein Frames [//]: # (internally, protein frames act as a number of procs; those procs are a tumor_create_act, which creates new tumors and determines their type; apply_act, which applies effects to the organ and parent body; growth_act, which determines what happens when a tumor grows or shrinks; and finally life_act, which is called on_life) The active part of genes - the part where it goes from "the heart, when I'm exposed to radiaton" to "grows into a mini-fusion reactor powered by said radiation".
