與合成人的大戰
一觸即發
故事發生於《戰慄時空》及《戰慄時空 2》之間，合成人殘暴侵占地球的時期，艾莉克絲．凡斯和她的父親伊萊在初期便組織了反抗行動。
七小時戰役落敗的煙灰尚未散去，17 號城居民學會了順服侵略者的統治，在合成人高聳入雲的堡壘「城塔」陰影之下生存。縱然人口四散各地，這之中仍有地球上兩位最足智多謀的科學家，伊萊．凡斯博士和他的女兒艾莉克絲，一舉建立起最初的反抗勢力。
您是艾莉克絲．凡斯，將就此點燃革命的星火
您和您的父親被遷至了 17 號城。之後數年，您仍暗中持續著科學活動，進行重大的研究，為少數英勇對抗合成人的人類製作極其寶貴的工具。
每一天，都對敵人的了解更深入一些。每一天，都為了找出他們的弱點奮力前進。
專為虛擬實境打造的長篇遊戲
Lean around a broken wall and under a barnacle to make an impossible shot. Rummage through shelves to find a healing syringe and some shotgun shells. Manipulate tools to hack alien interfaces. Tear a headcrab off your face and throw it out the window. VR was built for the kind of gameplay that sits at the heart of Half-Life.
Half-Life: Alyx supports a variety of play environments, locomotion methods, and input devices. However you play, we've got you covered.
