If you aren't already, there are a few things you need to make sure you shoot.

- The yellow boulder on the clifftop to your right, in the cactus section.
- The spotlight at the end. It's the second to last light on the left hand side.
- You need to kill the large UFO. That'll give you 1000 points.
- Also, apparently you can shoot the propellor of the airship. I've never seen it done, likely because it doesn't work in the PAL or NTSC version of the game. Some websites say it works on the PC and Japanese versions of FFVII though, neither of which I've played.
