I had a few listeners over at the house for my latest arcade party and one asked me about a game that I swear I knew what it was. But after searching through MAME and my memory I know what he is talking about exists but I can't come up with the title. So I figured I should throw it here and see if someone can come up with the title.
It is a space/flying shooter similar to Galaga or Galaxian.
A central theme is that you are adding components to your craft like bigger boosters or wings etc. to make it more powerful.
