最恶心的奖杯,通关(第100关)以后就剩这个了,本人第181关才解锁的奖杯。
发下诀窍:
During regular waves, occasionally you will see a saucer pass along the top of the screen. Shoot them down. They typically carry decent cash bonuses.
Note that this achievement does not count the transparent yellow saucers in the bonus levels, only the ones in regular waves.
Some tips:
-These achievements are not cumulative over total playtime. This must be done all in one playthrough. Starting from a later world, or getting a Game Over will reset the counter to 0. However if you save and quit, your progress will be stored for that playthrough (and that playthrough alone).
-If you're about to miss one and you can spare a Smartbomb, use it.
-Extra Bullets and Addon upgrades are your friends. The more firepower you can throw at it, the higher your chances of hitting it.
