I personally never beat the game (and all my old Nintendo Powers got damaged in the flooding in 2012 in my area, 20 inches of rain in 6 hours on that fateful March morning). I do know the game is easy to get lost in if you take time away from it. The lack of color also really added to the atmosphere of the game, dark and brooding, teeming with life forms that can kill.
Yes, I lost the NP that had the map, but Nintendo Power mags can be found, page by page scans if you look around for them. You can get entire issues that way, I had issues 1-29, never owned 2-28, but my old external HDD died, thereby once again wiping out Nintendo Power, Gamepro, and EGM magazine scans I had downloaded for reading purposes.
