I make another attempt again, but this time, I tried that apartment boss trick you showed me and it did work like a charm. Then I found out just now that the apartment door does not allow Quaid to exit until the small monitors (on both sides of the big screen) reveal Richter coming out of an elevator. I'm afraid that is how you know the stage can be beat. The image below is the exact frame where Richter starts coming through the elevators (monitors):
And what's funny is sometimes if Quaid keeps fingering the gun lady between her legs, more than she could take within mid air, she may not be able to give him her gun. For the run I'm doing, I did a little entertainment by "power-punching" her to the ground like it was real. She didn't drop her gun, and as soon as it came to the frame where Quaid was free to exit, the stage was complete and little to no frames were needed to get to the exit. It was within precise!
And now, I have to get serious with the rest of the run, I am trying not to give away a lot of frames plus I seek a little further improvement. I might score 5'29 but that is hard yet extreme work. We're gunna keep tearing up this game without holding back!
