About

Both are standalone narratives, and no knowledge of the other title is required to play this game. If characters or names from 计划 Projects appear again in other works by the creator, they should be regarded as separate reinterpretations.

CG/Video Playback Optimization
You can now choose from three different Windows video playback modes in Settings, allowing you to switch based on your device configuration:
Default / Media Foundation: The recommended default option. Supports hardware decoding and generally provides good performance and compatibility on most Windows devices.
Compatibility / DirectShow: A traditional Windows playback mode that may offer better compatibility with certain video formats or codec environments. If you encounter playback issues with the default mode, try this option.
Streaming / WinRT: A newer Windows playback mode with better support for streaming media. You can also try this option if the default mode causes stuttering or compatibility issues.
If videos in the game experience noticeable stuttering, black screens, or other playback issues, we recommend switching to a different playback mode in Settings to find the option that works best for your device.

In this dystopian parallel America, the “Nodomain Consortium (N.C.)” has overthrown the traditional government. The current United States is divided between two major powers: the militarized "N.C. Government," which controls most regions with an iron grip, and the remnants of the former regime, known as the "Old Government." Beneath the surface of peaceful coexistence, a fierce power struggle is intensifying… In this world dominated by alienation and authoritarianism, how will you, as a reformist, make your choices?

A visually striking near-future aesthetic
A carefully crafted blend of Brutalism, retro-futurism, and Wabi-sabi design styles brings each region to life with its own unique and harmonious visual identity. Complemented by custom-composed regional soundtracks, the result is a truly immersive experience with no repetition.
Deeply developed character ensemble
From a seemingly submissive special ops soldier to a sharp, enigmatic base commander bound by duty, each character hides a layered emotional core and a captivating backstory—waiting for players to uncover.
Rich world exploration
Discover hidden character dialogues, classified documents, and military files during your freeform exploration. Every room conceals forgotten secrets, and your deputy Osprey will provide professional analysis of all materials you collect.

非常喜欢老师的作品也祝老师身体早日康复!我愿称之为本年度到目前为止我心里的最佳,从demo开始等了一年但是很值得!大家都去玩啊啊啊,如果喜欢,或者想要尝试反乌托邦作品! 【ps:我第一次看到描写奥奇拉的那句话时感觉非常被打动,整个人一激灵,很喜欢啊很喜欢——在她身上有一种新的决心,一种隐藏在冷静表面之下的强烈意志。】 我非常非常喜欢《寂静谷》这部作品,它让我重新确认了一些我很在意的东西。 权力不会消失,人的攻击性不会消失,控制、仇恨、报复也不会消失。受害者不会因为受过伤就永远正确,掌权者也未必从一开始就是某种纯粹的怪物。很多宏大的主义,最后都藏在非常普通的日常瞬间里。 我们每个人大概都一直在和这些东西搏斗。有时候赢,有时候输。第二天再继续。 一个让人真正想要的世界,绝不会是一个已经彻底解决所有问题的完美世界,而是一个还有纠错空间的世界,一个任何秩序都可以继续被质疑、被修改、被重新协商的世界。 一个人不需要先把自己变成怪物,才有人愿意听见他的痛苦。 一个非人的存在,也不需要先证明自己足够像人,才值得被爱。 一个掌握权力的人,包括未来可能掌握权力的我自己,也不能永远站在别人无法触及的位置。 我还是会想到那句贯穿这部作品全文的话:清算者终将被清算。 权力是如此反复无常,而一切又似乎都和权力有关。个人的力量很难真正撼动它,但这并不构成什么都不做的理由。 我还是想活下去。 活得更久一点。 想看清楚更多,理解更多,思考更多。 如果有一天我真的拥有了一点力量,那我希望自己可以用它让一些事情变得更好。 如果我这一生也看不到最后的结果,那也没有关系。 我可以相信未来的自己,未来的后辈,未来的人们,未来的世界,未来的一切。 我不知道未来最后会变成什么样。 但它还没有被决定。 至少对我来说,这已经足够了。
奥奇拉 愿你如太阳般燃烧😢另外这三个女人之间的选择感情立场纠葛很美味很劲呀。。

霸权、强权、极权的世界里,每个人都是体制的俘获者,善恶并非绝对,反抗也未必是新生,顺从与温和亦不全然是懦弱。强者被规则捆绑,享受权力,弱者被命运物化,不过都是秩序下的囚徒。重建新秩序的方法不是“我”,而是“我们”。
好牛逼的世界观
4小时通关,基本把每个人物和每个点都探索了。很好的故事!本来冲着美丽男同【?】来的,但是不知不觉间被故事吸引了!!!游戏模式比较简单,基本是线性发展,喜欢看故事的可以直接冲! CG都好好看啊!!!!!能不能出CG收集功能,让我回味埃尔凡和鱼鹰的美丽CG吧求你了orz 结局停留在这里也很好!有点白描的意思!但是!!!!!!!我强烈要求制作组出逃脱后的甜蜜DLC!!!!!我要DLC!!!!!!!!我要看埃尔凡和鱼鹰同居生活!!!!
非常震撼的剧情,非常深刻的内容以至于我个人产生了一些哲学迷思。虽然体验下来体量比较小几个小时就能完成,但是剧情丰富,世界观阐述的非常清楚,人物细节补充的很好,冰山一角更引人深入思考。本作的人物塑造非常传神,每个角色都有自己的人格魅力。在我这里属于是可以细品的精品佳作。 强烈推荐! 附上一些不太顺畅的游玩体验,游戏内没有地图,有时任务卡中没有具体写出在某区域的地点时,让人找不到地方。 关于地点的移动模式也许是游戏想特意塑造的特点之一,但是不能快速移动还找不到地方团团转让人有点头疼,索性地图比较小多转转还是能找到。
无论是整体结构还是画风和文本都非常之美味啊,思路非常清晰,下一步游戏开发建议做的更复杂一点。感情线希望更细腻一点,后续日常给我端上来啊!!!!整体导向没什么说的,很吃这套,剧情太短了,不够看,我阅读比较快,两三个小时就结束了
非常好玩,文本和角色设计都很有意思,四五个小时的体验流程正好啊短小精悍的感觉,写的特别好看的我很爽,埃尔凡和奥奇拉感觉是不同的非常有人格魅力的领袖角色,其他的配角线也写得特别饱满人物弧光什么的都有,总体来说非常推荐购买游玩,不多说了我要给我朋友也送一个
实在是太有文化了,太宏观了,太结构性了,结局的好草率,虽然我明白作者已经为这个结局尽善尽美了,包括一系列震撼人心的演出,以及宏观的世界观构造,我真的很喜欢这种未来科技感十足的美术风格和地图,至少故事上是讲清楚了,而作者也对角色功能剖析自省得很,但展示上也许还有空间。我真的是冲角色来的,但要我抛开美术,我应该最喜欢女同三角恋的那句“上次我们的床”吧,鱼鹰和奥尔凡之间的化学反应有点,中气不足,从对方臣服之后他两只剩功能性而没有张力了,也许作者再出个DLC或者加个弥补房间我会高兴更多啊!
希望你自由,希望你幸福,恭喜你找到了生的意义
