Duke Nukem 3D: 20th Anniversary World Tour

In the Episode 1 level ‘Red Light District’, as soon as you start the level, activate the cheat menu and select ‘Give All’ (this will give you all the key cards for the level without having to find them). You can turn ‘God Mode’ on as well if you’re so inclined to make it easier.

From the beginning of the level, follow the street around two corners to the bar. Use the yellow key card to enter. Follow the entrance up to the pool table room. Walk past the pool table and take the second right up an incline. When you get to the door on the left, use the red key card and enter the dance area. Walk up to any of the dancers (there’s one in front of you as you enter) and press to unlock the achievement.
