This walkthrough is from memory, so I apologize for any mistakes.
Bare bones walkthrough (stuff needed to complete the game):
1) search your room, get the pulse pistol, the control ring, and the will tamer.
2) Go to the foyer, enter the party.
3) socialize in each of the rooms.
3a). Talk with the butterfly crew woman. She'll leave for the hangar (more options for her in the advanced walk through)
3b) use the control ring on the woman in the center room. You'll take her back to your room, she'll mind-whammy you, and you'll end up with the liquid hypnotic (check your inventory and examine it). Head back to the party.
3c) You'll run into a woman who invites you to the generals quarters on c deck. Do not go. Go to the bar and exhaust all dialog options with jack and the woman. Now go to c deck. North is the generals quarters. There is a robo-bimbo in there- best to ask about her specifications and leave, though there are a couple ways to deal with her in the advanced walk through. Now either go south or explore ( I cannot recall if you can just go south). Tell the two horny officers that their friends are waiting for them upstairs).
3d) at some point in the socializing someone will say "the princess is on the 20th floor'. If memory serves when you socialize it'll be a busty Asian woman who says it. Go the the elevator. If you have faffed about for too long the elevator will be fried and you'll go up to the 20th floor. Otherwise it'll ask for a passcode.
3e) the marquesas will steal your will tamer after interacting with her. Go one room away, then back. Whatever you choose you'll end up with the door hacker.
(Note, I've found all four of these are necessary steps, except for 3d).
4) if you have done all of the above, Guame will be running around but you won't be able to approach him. Go to the bar, order a quivering quasar with liquid hypnotic. The bartender will strip,and draw a crowd. Go to Guame. No matter what you say Guame will demand you sleep with him.
5). Go back to your room with Guame. Go as far as you can without submitting, then shoot him with the pulse pistol. Use the hard light holo belt on him (this isn't necessary, but it makes this next bit easier).
6). Nikolai runs up. Be honest with him and you enslave him. Get his glasses and wear them.
7) use the elevator to floor 20. If you are early you can pulse pistol the guard, if you are a little late you can pulse pistol the guard and hybrid.
8 ) go into the princess room. She'll either be furiously masturbating (and I just learned my spellcheck doesn't know the word 'masturbating' because it was programmed by Mormons or something) or enslaved. You'll get in a fight with the hybrid, you can sink deeper, and if you have enough willpower you'll knock the hybrid out.
9) deal with princess however you'd like (pulse pistol, Will tamer, etc)
10). Go down to the hangar and help the butterfly crew woman with repairs. Will tame her.
11) Go up to corridor a. Use the door hacker on the locked room due north of you. Go in and an angry ship captain will summon her crew to deal with you. The captain will summon your slave and be captured.
12) Now you have a ship, a captain, the princess and the codes. Talk to the captain and win.
In between steps 11 and 12 you can cleanup a bunch of the side quests, and there are specific options available to each of the different characters, but once you know how to get to the end you can often puzzle them out at your own leisure. For example, if your are tech savvy you can enslave that guy in the beginning, take his tools down to the bimbo-bot, and deactivate it, netting you the bimbo-bot outfit. If you chat with the mistress at arms you can get access to b deck, which lets you get the slave harness and the mind blinder, which, if you have the slut spiral pills from the belly dancers wardrobe, will let you crush the hot redheads resistance. If you get to c deck early, search and locate the maid outfit and wear it, you can... Well, you get the idea. There's an invisible sneak thief running around, emp grenades, a medical bay (which I don't think you can do anything with, but damn if that isn't a hot doctor), various outfits, a couple transformations, alternate paths to almost every necessary part, etc. it's a great game. I'm excited to see rl3
Btw- I know there was a poll a while back but I'll just say I think the bonus character is great.
you can also optimiZe a little depending on your character- if you are turned into the baroness' girl -toy, you can talk to the couple at the bar as soon as you get to the party and then take the baroness to her room- you'll dump out on c-deck, so you won't need to socialize until you find the generals side quest thing.
Anyway, I hope that helps.
