Three tattoos, two different navel piercings, and that's about it at the moment. It was found in the code however that there are several more "slots" for tattoo and piercing variables for Lena, Holly, and Ian.Haven't played the game in a while, are there more options to customize Lena now or still just the three tattoos?
My personal opinion: I think they're a "just in case" code, if Eva does decide to give Lena more tattoo options. I could see Ian getting maybe like a tribal if his chad variable is high enough, but I don't think Ian will get several options. Same goes for Holly, she might get one or two later in the game the way Eva from GGGB could get a couple, but Holly currently has 5 different variables in the code for tattoos plus a couple for piercings, Lena 10 plus several more for piercings, and Ian 3. Those numbers might be a little off, as it's been a while since that code was posted and I didn't bother to save it. Regardless though, those are way more for all of the characters than I personally would actually expect any of them to get.
