Game Info:My intent is to enhance the overall playability of the Metroid engine by providing an entirely new adventure. I have attempted to keep this version of Metroid true to the spirit of the original by making some tricky secrets and convoluted mazes.
Where my version departs from the original Metroid game is the following:
Much larger overall map; easier to get lost
Secrets are in some cases harder to figure out
Placement of enemies is much more devious, requiring you to plan how to get past them without getting the crap kicked out of you
Respawning occurs with not just Zebs; it also occurs with tougher enemies such as Rios
All non-missile items are CRITICAL to winning the game
Important items are locked away much more tightly than before
Other Notes: Metroid Master is a rather lengthy game and you will probably want to save your progress at some point. The built-in password system will allow you to keep any abilities and items you've collected, but for the added functionality of save states which will allows you to pick up from the exact point you left off, you can download an NES Emulator and a Metroid Master game patch which are found on the main Metroid ROMs page.
