敌人的血量随章节指数增长，你的火力涨得更快。每一章开头被逼到防线，升级之后把整片天空扫空——锯齿形的成长，一次又一次。Enemy health grows exponentially every chapter, and your firepower grows faster. Each chapter pushes you back to the wall; a few upgrades later you sweep the whole sky — a sawtooth of growth, again and again.
点击战场上的月球、行星、太阳、恒星与星系，把它们改造成独立开火的武器。每一种都有自己的轮廓——换章之后，它们缩成核心旁的星环，继续开火。Click moons, planets, suns, stars and galaxies on the battlefield to convert them into weapons that fire on their own. Each has its own silhouette — and after every leap in scale they shrink into rings around the core and keep firing.
没有停顿的波次，敌人源源不断地涌来。你越强，吞噬得越快。No pauses between waves — threats pour in nonstop. The stronger you are, the faster you devour them.
每座炮台都在独立开火，扇形铺开，打向每一群威胁。Every turret fires on its own, fanning out across every swarm.
点击任意敌人，所有武器、所有在途导弹同时转向。Click any enemy and every weapon and missile in flight turns at once.
每一次击毁都会推动背景点阵，整个战场都在回应你。Every kill ripples the dot grid. The whole field answers you.
