I believe to get to those scenes, you first need to lose to Dredd in a game of cards and have no money to pay your debt. It cuts to the stripper scene, then Dredd will ask if you wish to party with him and the crew. Once that's done, you can go back and party with Dredd (& crew) any time you wish. But full discloser, its been almost a year since I dealt with Dredd and that part of the game.
Not sure it's like that because I've never got without money when loosing to Dredd. After dancing the first time Dredd tells me that I can go and dance as striper whenever I want. When I do that, I usually loose -1 Masculinity.
Point is, I don't recall when and why exactly that option (Maurice the serum dealer) showed up! Thanks anyway! Maybe I will try by starting another game to check it anyway.
Its up for playtesting with the backers, and I had expect it to be rolled out to the public already (with the add for the Beach). But recently she added the MilkMaid pill demo for playtesting so it may be a couple more weeks. Its going to be worth the wait, because it adds so much to the game.
