Combine this with the fact that the best way to rack up your score, aside from hostages and big points like the ships, is to take out lots of enemy troops. Problem is, you have to be really fast and kill them in time before they run off the screen. But most of the time, this contradicts the best strategy of the game which is to take everything very slowly.
I think the thing to realize is that you don't have to necessarily take each screen slowly, you just need to know when to scroll the screen forward. Also, shooting rockets diagonally with the thing that makes them split up (I think it's the T powerup? Not sure) is a great way to get enemies that leave the screen quickly. There are a few cheap parts in the game such as the waters where the enemies can spawn directly underneath you in two places. For the most part you just need to either remember those spots or stay out of the water when scrolling the screen.
The hardest spot in the entire game, I think, is taking out the 4 turrets before the final boss. Seriously, how do you guys do it? They took like 15 hits each with my gun/grenades. I'm guessing they go down quicker with rockets.
What I do is either run in a U pattern from each outside turret and bomb those outer turrets first then work on the inside ones. Or I go to one side and move around just enough to slip and dodge the rockets but not too far out of range. I usually use the U technique though as the other way can be a lot riskier. Either way,they are a big pain...especially if you are having to use just grenades.
