At the end of stage 1, right before the boss 'Confrict' closes in, you will see a bunch of police cars. They will be destroyed by the boss anyway, so it seems not to matter if we shoot at them first or not.
The only difference is, that if 'confrict' does the job, they release a golden score medal for each car you preserved. Try not to save too much of them, since they are all from the same wave. So your score level will upgrade only 1 step and if you are unable to catch all the medals popping out, your score level gets lost.

Use your smartbombs to crack houses and bridges. They often contain large numbers of score medals.

Examples:
- The glass roof in stage 1
- The big plane in the 'airport' stage - medal galore !
- The "street" in the 'sewage system'

Stop the subway train in stage 1 with a smartbomb to obtain a bunch of golden medals.

Take down the escalators in the 'airport' stage with your smartbombs for score medals.

In the sewage stage, you will fight some vertically shooting laser guns. You can just shoot at them, that's one way to destroy them and to receive big main shot items. But in order to receive score medals you should smartbomb them while their flipping platform is faced down.

In the sewage stage, you will pass some green containers with tanks driving out of them. Use your smartbombs to release some treasure.
