This is a video walkthrough / playthrough / runthrough / etc of Metroid II: Return of Samus for the Game Boy. This is a 100% item run.
I'm not sure if the route I took was the fastest one or not. Everything works out in the end, so I'm happy with how it turned out. I do save a few minutes of time perhaps since I get some missiles using the bomb jumping trick. It wasn't really needed, but I figured I might as well.
Also, I'm sure there are better ways of defeating the various types of metroids than what was shown. I might have been a bit careless during some encounters, so I apologize for that.
