Buzz Lightyear Galactic Hero Secrets
The secret is to hit as many of the 100,000 targets as possible.
The first is in the first room, on the left, on the inside of the rock-em-sock-em robot's left (far hand). You can just see it in the distance of this picture. You need to start shooting at this as soon as you get control of the car and before you enter the room. Once you're in the room, it is very difficult to get the angle right. It is somewhat easier to hit this from the left seat of the car, but it can be done from the right seat.
There's a claw hanging from the ceiling that is also worth 100,000 points, but I don't have a good picture of it.
Then, in the next room (the battery room), aim for the target on the bottom of the first time you see Zurg. He's on the right side of the car. This also, is a hard target to hit from inside the room. Much easier to hit as you are leaving the room (turn your car around and face backwards).
Supposedly, there is a 25,000 point target on the volcano and another 100,000 target on the on the worm-like creature that sways on your right side. I can't remember which order these fall, though.
Finally, there is a 100,000 point target in the video room that I've not be able to find, but my daughter found it and got 999,999 before her brothers (annoying them to no end). It supposedly is near the door out.
Finally, if you're lucky enough to be stuck (this ride seems to stop all the time), then you might be in a good position to hit stuff. Shoot for things far away.
