Old topic, but what the hey.

This guy, he's trying o defeat White Glint, so I'm assuming he doesn't have many parts at his disposal.

I recommend dual machine guns for arms (HITMAN, MOTORCOBRA, whatever) and dual AS missiles for back weapons (LAMIA, LAMIA2).

Now the trick is, you must let Otsdarva do all the fighting until


Just let him do all the work.

Then, once that's over, just go head-to-head with White Glint, he's weakened (sometimes considerably) by the fight with Otsdarva, so it's never really too hard. Use the machine guns for head-to-head fighting, then if White Glint flies into the air, just fill the sky with AS missiles, you don't even need a lockon. He'll die soon enough, and you can get on with your game.

Though I'm assuming you've already beaten him.
