The face editor is where I lost twenty minutes. You can drag her eyebrows into this perfect little scowl, or make her eyes roll back so far it looks like she's having a religious experience. Then you realize you spent all that time on the face and forgot to take off her jacket. Classic.
Android 18 XXX Simulator is exactly what it says on the tin. You get the blonde cyborg, a bunch of sliders, and permission to go nuts. The customization is deeper than it has any right to be for a browser game. Hair up, hair down, earrings, that little denim vest thing she wears, all toggleable. You can make her look pissed, bored, or like she just remembered she left the stove on. The DBZ parody angle means you can also mess with her power level aura, which is a nice touch for the lore nerds who want their hentai with a side of canon.
The actual fucking is fine. Nothing groundbreaking, but the poses are solid and the animation loops don't make you want to claw your eyes out. What surprised me was how much the expression system changes the vibe. Same position, but with her glaring at you versus her mouth hanging open like a broken mailbox, completely different energy. The sound design is whatever, just the usual wet slaps and moans you've heard a thousand times. No complaints, no awards.
One thing that bugged me, the color picker for her outfit resets if you switch tabs. Why? Who knows. Browser games, man.
Anyway, if you've ever wanted to see Android 18 in nothing but her boots and a look of pure disappointment, this is your jam. Just don't expect a story mode. There isn't one. It's a toybox, not a novel.
