So I decided to be different and not make any public mention of this until I had a proof of concept ready to go. So here's a quick video.
This is still in very early testing, you will notice that the Vault-Boy still looks like a cyborg instead of a mutant. A question mark is missing in the confirmation dialogue. A few other minor errors. I'm not sure how the player will acquire the ability to mutate, I want it easy to access, but require some investment. I'm thinking a simple perk that requires you to be irradiated, or something similar. Once you acquire the ability to mutate, any time when you are not in combat, you can simply press 'M' (configurable) and the mutation menu will appear. As seen in the video, the cost of mutations is based on what you get, not where you put it. So if you want to go in and re-arrange your mutations, it won't cost you anything. The cost to apply a mutation is "Mutagens" which are acquired over time, but perks and other situational stuff can cause it to increase faster or even give instant bonuses. I eventually want a unique upgrade system that allows you to incrementally improve mutations. The easiest way to do it would be to use message boxes that say which upgrade do you want to apply, but I would like to implement a real UI with a tree structure (think Diablo 2 skill trees, or maybe World of Warcraft, or something similar).
Done babbling, any ideas thoughts suggestions? This is NOT for TTW and is actually a PN based mod that I've had kicking around since about 2009...
like a head mutation, a body mutation, a hands mutation, a legs and/or feet mutation. Also maybe different levels of mutation, like to have level 1 you need a Perk (Let's call it Mutant for now), and to have a mutation level 2 which improves a bit on the lv1 one you need Mutant second rank and so on... That way you can decide if the player aquires the skill to mutate by sacrificing a perk or by doing something ingame that will award that perk
