iOS 平台上最好的塔防游戏，Kingdom Rush 的音乐和画面有很浓重的欧洲中世纪风格，看起来就像一部略带魔幻元素的动画片。每局的主题不一样，截图所示的比较「田园」，后面也有雪山和黑暗场景的关卡。

一群不知从哪里来的半兽人、食人妖、邪恶巫师与其他坏家伙们，突然从王国的边境闯入，它们任意攻击国境内的村庄造成极大的伤害。王国为了应付这个危机，组织了一只卫队，拿起各种武器向邪恶的怪物宣战！

The world's most devilishly addictive defense game is back - welcome to Kingdom Rush: Frontiers!

Bigger and badder than ever before, Kingdom Rush: Frontiers is a whole new level of the furiously fast, enchantingly charming gameplay that made the original title an award-winning hit. Tap your troops through an epic (mis)adventure as you defend exotic lands from dragons, man-eating plants, and ghastly denizens of the underworld -all with flashy new towers, levels, heroes, and more goodies to help you crush your foes to a pulp. (Don't worry, we've still got all the good ol' stuff from the last game, too. It's vintage now.)

Kingdom Rush: Frontiers packs in so much content, it's like a fully upgraded artillery blast of mouthwatering, pixelated joy launched right into your smiling little face... and it hurts so good!
