Here is a video that goes over basic combos and tips for Maxima. It's very useful for new players.

A friend of mine, Anues*, did the translation of the text in the video. He did an excellent job.
Here is the link to the translation: http://www.mediafire.com/?8csyaw3r5zexh3g (http://www.mediafire.com/?8csyaw3r5zexh3g)
Note: The translation does not include the CH section OR the HD section, but because they're visually and literally self-explanatory, I don't think it's necessary.
EDIT: My friend is almost done with the CH section, Chapter 2, and Chapter 4. Will update the link when it's all done.
