About
‼️This game contains violence, gore, and extreme content. Please read and play with caution.‼️

Unknown time. Unknown place.
The moment the nameless girl opens her eyes, her destiny is already set in motion. With no prayer nor blessing to guide her, she steps alone into a colossal ruin choked with deranged machines.
After unbearable despair and the unending cycle of slaughter, the wavering blue light of her will is shattered, stolen, and trampled again and again, yet she continues forward.
Between cruelty and salvation, the tolling of the Church’s bells cuts through the world, and as their maddening echo strips away the last restraints of flesh and mind, the world begins to shift.
In the depths of this nightmare, she sees it:
Two souls appear, reflections of each other's shadow.
"Are you ready to make the ultimate devotion?"
A dark fable of existence, annihilation, terror and pleasure

Protagonist
CV: Momoka Kosuzu

A girl who has lost both her name and her memories. To fulfill the mission entrusted to her, she explores a vast ruined city while battling the many hostile entities created by the organization known as the Church: a group that once reshaped her body into a living weapon. Each fight sharpens her skills, strengthens her body, and leads her to new and powerful gear whose potential she gradually unlocks.
By following the memory fragments scattered throughout the map, she draws closer to the truth behind this devastated world. The companions she meets along the way give every step she takes through the ruins real meaning. In time, those connections will become the signposts guiding her toward the "end of fate" that awaits.

纯想色色的可以不考虑,色情内容和CG都差不多,没有自由存档点死一次要跑好远,被怪打死才有CG,然后还有很多陷阱还都是秒杀的,玩法也挺无聊就推图,剧情我没怎么看但游戏画风挺不错,总之可玩性和色色都不是太好,喜欢这个游戏画风的可以试试但如果是买给二弟的那还是算了吧
[h1] 별점 : ★★★☆☆ [/h1] [h1] 한줄평 : 기괴한 캐릭터 디자인, 그보다 더 기괴한 무기조준 방식 [/h1] [h1] 신사력 : 중꼴 [/h1]
有可玩性,带点略重口H ,弟弟说不错
神作
游戏还是比较难的画风不是很喜欢感觉建模也就那样了作为一个黄油啊你CG不能做好点吗大部分全是砍瓜切菜不知道啊搞啥性情部分比较偏少啊而且内容还是比较少的而且这游戏只能在国外去买价格都是偏贵的还不如买那个sinsister2呢人家CG比你做的好而且建模还很不错打折的话也只要42你这东西加个捆绑包的话卖我59不如我推荐的
好玩遊戲使我San值起飛 R18G廚極度推薦

美术风格很喜欢,画廊演示做的很棒,机械飞升完美,但三个CG一般。游戏性开始还可以,往后立刻断崖式下降,后期堆怪无脑折磨。而且明显感觉越到后面鬼脑逐渐无力,H内容越来越扁平。希望至少可以类似“投稿”,征集一些关于H内容的意见。目前感觉单纯血腥重口,猎奇方面深度不高,鬼脑的想象力还是不太高,对R18还是没太放开。
終於解脫這場謎樣賽博噩夢, 不得不說難度也太... 我只敢玩簡單 不過上次對這種橫向卷軸的2d動作遊戲, 還是國產的惡靈寄生, 但他是地圖設計非常強大的作品, 也有一定程度的趣味性, 本作就是純粹的戰鬥操作, 地圖也不太有任何難度, [spoiler]除了陷阱之外[/spoiler] 福利還算普通, 煩躁的感覺無非是被怪量煩死的問題, 尤其是某些前景建築物擋住怪物的時候, 看不到又一直扣血 不過整體來說算好玩的, 也聽說在開發第二代了, 我等不及要在遭受一次這樣的折磨 原因無二, 本作的劇情還真的是謎語人, 蠻有趣的推薦
太清淡了
