Galaga

Galaga is a vertical arcade shooter from Namco. You control a space fighter at the bottom of the screen, scrolling left and right in order to avoid oncoming bombs and kamikaze attacks from alien invaders--and to fire your own missiles to fight back!

There are an infinite number of stages to progress through. Every third level is a "challenge stage" in which you have a free chance to shoot as many aliens as possible and rack up bonus points.

Certain aliens have tractor beams they can use to capture one of your ships. If that wasn't your last "life," you can try to shoot that alien down and recapture your ship, giving you two ships at once and doubling your firepower.

A summary screen appears when the game is over, giving you both your final score and you final "hit ratio"--the number of missiles fired, enemies destroyed, and the percentage of targets hit.

《大蜜蜂》是南梦宫推出的竖版街机射击游戏。玩家将操控屏幕底部的太空战机，通过左右移动躲避外星入侵者袭来的炸弹和神风特攻式撞击，同时发射导弹进行反击！

游戏包含无限个可推进的关卡。每三关会出现一个 “挑战关卡”，玩家可以在此无风险地尽可能射击更多外星人，累积额外加分。

部分外星人拥有牵引光束，可以俘获玩家的一架战机。如果这不是你的最后一条命，你可以尝试击落那架使用牵引光束的外星人，夺回被俘虏的战机，这样就能同时操控两架战机，火力翻倍。

游戏结束后会显示结算界面，展示你的最终得分和最终 “命中率”—— 包括发射的导弹总数、消灭的敌人数量以及命中目标的百分比。
