Okay, I chose to see what I can pull as this becomes my next project. It is so obvious that quite a few have started this attempt and not found the nerve to finish it. Not very many updates were given, until now.
Based on the video from speeddemosarchive.com, that player picked a pretty good route to the Cobra commander, while killing some of the bosses and mini-bosses seemed like a piece of cake. Here, I chose to take the exact same route
I already learned some of the techniques from Inzult's first stage, but this is the road to a building where 8 women need to be set free.

There can be improvements along the way if any. However, this is a first draft I will be doing just to see how long the game will be beat roughly. I predict 7:50.

Updated with a new strategy technique against a mini-boss that launches something that looks like band-aids. =/

The key here is to keep your distance from the mini-boss in the "women-taken-hostage" building before going into a room with Overkill, it's main boss. The strategy involves shooting bullets as he walks up to you, then switching to fists to knock the mini-boss backwards, then immediately switching back to gun (Gen. Hawk automatically punches upon switch, I thought it seemed useful almost). The key is also to ensure you stay away from them look-alike bandages that shoot across the screen. Gen. Hawk can score several hits from behind the mini-boss should it decide to launch "bandages."
