Kazutaka Kodaka and Kotaro Uchikoshi join forces for the first time to deliver the ULTIMATE adventure game! 15 students are tasked with defending a school from grotesque monsters for 100 days. Can they make it to the end? And will they survive long enough to uncover the truth?

Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 2.71/day in the week to Aug 2 → 2.43/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Takumi Sumino is a totally average teenager living in the Tokyo Residential Complex, a place where every day is much like the last and nothing bad ever happens. All that changes when freakish monsters attack the town and start wreaking havoc. A strange creature calling himself Sirei appears and offers Takumi the power to protect those he holds dear... All he has to do is stab himself in the chest!
The next thing he knows, Takumi is in Last Defense Academy, a school in the middle of nowhere surrounded by a wall of otherworldly flames. He and 14 other students have been drafted into the Special Defense Unit, a team tasked with keeping the school safe for the next 100 days. How much are they willing to sacrifice to take back their normal lives and save the world from the grotesque school invaders?
The curtain rises on 100 days of war and despair...
Takumi's choices will decide his future, but there's no telling what kind of consequences these decisions might have...
When the invaders attack, it's up to you to protect the school in SRPG battles.
Use each student's unique Specialist Skills to turn the tide of battle in your favor!
Spend time with your teammates to deepen your bonds, or explore the wilderness and ruins outside the school.
You can even use the items you find to craft gifts and get even closer to your allies!

鲜血淋漓篇给我看笑了
虽然我知道现在写这篇评测可能没人看得到,但我决定还是把它写下来,或许会有人留意到呢? 总之,这篇评测比起说明这个游戏是否好玩,更倾向于向你介绍这个游戏是否适合你。 首先整个游戏的噱头非常足,100条故事线与100个结局,这个乍一听很牛逼但仔细想就会感觉到有一丝丝不对劲的设定是不是非常耳熟?it just work,是的,虽然嘴巴上这样说,但实际上剧本可以用水分十足来形容。嘴巴上说100个结局,什么叫死了也算结局? 时空轮回与多条时间线的设定就导致上面提到的水,把整个游戏变成了原价238元的大型盲盒。运气好一些玩家可以玩到一些悬念十足的故事线,获得不错的体验。但是运气烂一点的可能就直接进入幸运之匣篇这种全程大富翁,剧情不明所以的烂线,这也让整个游戏的作品变的相当参差不齐。它甚至有条线硬生生的让玩家打战旗打100天,我都不知道应该如何形容这种感觉,期待着后续会有什么惊天剧情,结果就这样莫名其妙的结束了。 而且这种盲盒的设定还十分影响玩家对悬念的期待值,举个例子——鲜血淋漓篇里发生了连续杀人事件,起初不知道犯人是谁,后面还突然变成了丧尸片。如果一开始玩家走的这条线可能还会有些期待值,想要明白究竟发生了什么。但在此之前我就已经先通关了厄运之匣篇,在杀人事件发生的时候就已经明白了真相的大致,这点非常不好。 虽然存在着剧情锁的设定,但也仅仅是锁住了与主线相关的几条线,别的完全没碰,非常影响沉浸体验!而且男主真的就是个睡神,剧情里除了睡还是睡,外面敌人打进来了睡,学校里死人了睡,好朋友死了睡,总之就是睡睡睡睡。 总之,如果STEAM有个中评的话,我应该会毫不犹豫的把这个评价给予百日战记。因为本作也确实拥有许多条不错的剧情线,像是让我捧腹大笑的后宫线,又或者真相大白线与全员生还等等我都非常喜欢。但在此之前整个游戏给予我的体验是灾难性的,像极了在玩一种新型的SM,小高和打越是S,我就负责当那个水灵灵的M,小高给我一鞭子我疼的子哇乱叫的时候打越过来安抚我,然后打越又给我一拳,在我哭的时候小高给我糖吃。 什么?你问战斗?本作的战斗它有着非常高的上限,可玩度十分丰富。但是制作组选择了下限最低的打法,即整个游戏在了后期完全没有什么全新的内容,前4个小时怎么玩,后面依旧怎么玩。整的就是神风敢死队,遇到BOSS了就让角色一个个送死然后主角上去开大结束。所以你问我它的战斗好玩吗?我只能说前面确实挺好玩的,但是要维持这套战斗模式一百个小时,剩下的只有疲倦。 所以如果这个游戏能够大幅度减少战斗,以及大富翁的玩法,那么整个游戏体验就会上升不少。但是多周目的存在又让玩家不得不去体验非常多大差不差的前置内容,最后往往会让人如坐针毡,所以如果想要获得一个不错的游戏体验,你可以试试一周目的时候不看任何攻略打完,二周目之后看着攻略去打一些和主线相关的故事线。 还有,千万不要试着全成就,那里只有痛苦与腱鞘炎。

主线剧情还不错,真相大白结局骗了我2滴眼泪😭支线神屎二象性。打了跳过战斗MOD还是值得一玩的
Praise be to Gaku
so fun i like
ES DEMACIADO BUENO, su gameplay es adictivo as ♥♥♥♥, su historia es increible (aun que tiene sus puntos flacos) y VOY A SACARLE PLATINO
不好玩(我玩的時候已經有跳過戰鬥), 使用了一個非常糟糕的架構: 對於時間的概念有點奇怪,玩家的回檔到底是什麼, 主角在回到過去後,對於曾經經歷過的事件依然保持住一樣態度例如不知道,或者會出現一些意外但是明明 提前知道的資訊 ,對話中出現邏輯矛盾,即使角色在某些支線遭遇重大衝擊 , 主角的態度亦都貫穿整個故事(即使之前的故事遇到任何衝擊) 遊戲的代入感對我來說是對我很重要, 卻在遊玩劇情中要我使用他的ui瘋狂跳(十個分支,還沒有問題但是多個以上,就會開始迷失 我遇到了很多次 到達這個分支的時候 ,必需要首先要完成什麼什麼分支 嚴重影響遊戲體驗, 結果就是我只能偏歷, 所有可能的問題, 更可悲的 很多分支的結果與他的問題是沒有任何關連的. 而且中間的其他"垃圾"線 (純粹指的是沒有額外資訊)的意義在是什麼 在知道其他線 需要 例如收集密碼 主角完全沒有反應, 學院有機會多人, 沒有任何溝通 做任何機器, 已經知道是入侵的真相 ,回到開頭 卻沒有表達任何事情, 反而殺人動機(防止劇透) 在殺人線 會回到過去影響自己 還沒跑完全路線 本來不想給負評的 原本想說忍著去 看了影片 ,看了結局當玩完, 結果每一次都完全不想打開遊戲甚至不想去找結局,直至半年後今天再看到忍不住,給負評
等弹丸的时候玩玩
The title is incredibly misleading. The developers of this game were doing waaaaaay more then a hundred lines when making this.
its the best video game ever
