Ever since I played the shareware version over 20 years ago, I was entertaining the idea of making a list of all the enemies and how much they earned me, out of curiosity. Now I'm spending more time than it's worth on getting the images and data, which can be surprisingly tricky. The list isn't complete yet, I'm still working on it. If you find a mistake, post a comment.

This refers to all the ground structures that don't shoot at you. There are too many and they are too minor to make a list of all. Destroying these buildings rewards between $25 and $200 per tile, there seems to be some correlation to how sturdy they are. The flimsy huts, that crumble after just 6 bullets, only earn you $25, while those metal silos, that suck up your firepower better than Kirby could, at least pay $200. That's $2400 for the whole thing, not bad for the first level.

Now this is the real stuff, about everything that flies, hovers, floats, drifts and levitates. Also a few things that roll, swim, crawl, hide or just sit there, because if you shoot at me, you ain't got to complain about categories. The enemies should be listed in order of their first appearance on rookie, if they first appear on a higher difficulty, I'll add them at the end of the sector. Weapons refers to what they attack you with. Standard are the yellow bullets. 2x4 means 2 turrets that fire 4 shots each, in other words, 2 shots simultaneously, 4 times in a row.
