Security Post

The security post which separates New Ark from Upper New Ark. It's not possible to sneak past them without checkup.

"Papers, please"
The first part is located in New Ark, placed in such a way what it's not possible to go through without checking up with them.

They would immediately reject Lust Doll if they try to go through while not dressed appropriately or armed. Otherwise, they would check the documents. As obtaining the legitimate documents is beyond Lust Doll's abilities, they can only try to use the forgery and pray what the fake wouldn't be discovered.

There are four kinds of fake passes, different only in name; there's no way to determine which one is "correct" before you try to use it, though if you save right before the entrance, you can just reload and try another one. If the fake is discovered, you lose the pass and gets fined by 100 and lose all fake passes in your inventory as you would be searched. Otherwise, you would be allowed to go further. Using the quality forgery (see this page for instruction]] guarantees what the fake wouldn't be discovered no matter what.

Each pass is one-time only, and gets removed from your inventory when you get checked up.

Medical checkup
After checking your documents, you would stand in the line (mercifully, the game skips standing in the line) and then approach a special machine.

As the locals are extreme prudes, they wouldn't allow any "horny barbarians" inside, so they have installed a tech capable of measuring your arousal. If it detects the high level of arousal, it would forcibly (and publicly) "de-arouse" Lust Doll, dropping their arousal to 0. It's possible to evade it, but it wouldn't let you through until you actually do checkup. The difficulty of dodging is 25+(Nim*5)%.

After passing checkup in one way or another, you're free go go.

Hall
From there, you can either go up and enter Upper New Ark proper, or return back to New Ark through a separate door, which would allow you to leave without going through the security post, as they only check those entering, not those exiting.

Scenes

 * If you try to go through while aroused, a special scene would play during medical checkup.
 * If you were previously arrested by Arlene for public indecency, then the next time you would be arrested for using a fake pass, she would be the one to arrest you. It would lead to a special scene, and you wouldn't lose the rest of fakes in your inventory (if you have them). This scene seems to be one-time only.
