有人在引擎里发现开发代号，有人感觉之前 20 周年纪录片里有暗示，然后有传闻说 Valve 在邀请员工熟人和亲属参加封测

现在 G-Man 配音演员又用 G-Man 声线发了个 “Another year already. Good to see and hear from so many of you. May the next quarter century deliver as many unexpected surprises, hmm? As did the millennium's first. And again time is fluid like music. See you in the new years!”，他上次 Half Life Alyx 出之前也发过类似的，这是时隔四年再次发推

最近半条命社区已经炸了锅了，当然也有可能纯属附会，哈哈
