NOTE: BEFORE READING THIS SECTION AND GOING ON, READ SECTIONS 0.0-2.3 AT LEAST BRIEFLY. I DIDN'T WRITE THEM FOR NOTHING! THEY HOLD IMPORTANT INFORMATION YOU NEED TO KNOW FOR THE REST OF THIS WALKTHROUGH.
Now comes the actual walkthrough of the levels of BC, from Area 1 to Area 12. Before read this, I suggest briefly going through BCHQ's page on each of the individual levels. THIS IS FOR BEATING BIONIC COMMANDO FOR THE FIRST TIME AND IMPROVING. If you're trying to beat this game for speed, turn to section 4.0.
As mentioned before, there are links to NSMs in the following pages. This section tells you how to view them. At the top of most pages is a link saying "Complete section corresponding NSM." That NSM shows the entire level.
