I jinked around the Master Boss' weapons as well as I could but was in front of that door when it opened! I started this level with 29 lives and the Master Boss exploded when I had 25 left. I hit each Boss with NK3000's 5 at-a-time until they exploded, then used just the Secret Weapon on ships and the Master Boss - ONLY when the door was Open. I turned all but 100 NK3000 rockets into plasma and had 1.9+ million plasma for the Secret Weapon. I went into the Master Boss battle as a cadet with a V05 ship, max'd highest laser and on down, 400 1200 plasma cost rockets and 380 1500 plasma cost rockets in store. Before each level I would repair ship, droids, replace any droids destroyed and replace rockets used before buying more.
On Droids, I bought repair, then battle, then laser and air raid as my ships allowed.

Also,when I maxed out a type of laser and rocket pair combo, I would save to upgrade the ship one type before purchasing more than replacement numbers of rockets. When I switched to the next type of laser for actual use, I had at least 3 segments purchased. I purchased laser to the greatest power of a type, and then purchased the next more powerful type, one segment at a time, while still using the max'd out lesser power laser. I DID buy all the missiles and lasers however, I started buying in pairs (a missile and the next more powerful) to a max of 100 lesser powered and 75 more powerful - changing up in power as the missiles seemed to be doing less of a job against the opponents (and starting to buy the next more powerful a few at a time in preparaqtion when possible). I know that this is an old game, and probably no one is interested, but I approached this - successfully - in another fashion.
