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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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!

因为编剧不一样导致每一条线观感都不一样,有的线太逆天,有的玩的挺不错,但总体还是好评的,不过这个最终结局只能说放飞小高
amazing experience. went through five stages of grief, happiness, madness, and all other emotions, in general typical kodaka game experience 10/10

百日战纪 千万别玩,玩了会度过一个彻底失败的人生 在我三周目通关真相大白篇之后还是要稍微更改一点关于这个游戏的评价,毕竟立意确实不错,最后的CG以及音乐也很感人,不过我还是那句话,我真是越来越搞不懂一周目的意义到底是什么,因为删去一些穿越元素和选项,把一周目的起始加上真相大白篇一样可以是一个非常完整的本体故事,并且从二周目开始基本上剧情和一周目就没有地方是一样的了,没必要在一周目里搞什么虚假选项罢,而且一周目为了强行让人玩二周目全员真的很蠢啊,没有一个人动脑,通关之后立马搜搜攻略玩真相大白可能还会好一点 下面就是我在玩完一周目游玩二周目途中的评价,我现在依然是这么觉得的 小高和刚在V3之后已经彻底不对劲了,本来我对百日战纪有所耳闻,我还以为是只是某些线路很垃圾,结果一周目就是一坨巨💩 整个篇章里没有一个角色有脑子,一个都没有,从头到尾一点点自己的思考都完全没有,就是单纯的被别人牵着鼻子走,说被杀就被杀说怀疑就怀疑,稍微点个火燃的就比山火还猛烈,甚至主角的摆烂不想思考都是写进文本里的,唯一会动脑子的时刻还是用来猜忌队友,为了强行拉二周目整个故事就是不断推翻重来想一出是一出,制造悬念感只会用最垃圾的一档谜语人塑造,可能制作组也知道但凡整个游戏里有一个人是稍微有一点点脑子,稍微会思考的正常人这个游戏只能写出1个小时的量,于是司马制作组到了二周目男主穿越回过去之后依然让男主不动脑子,整天想的就是“这样应该没问题吧”“可以吧没关系的”是他吗的人类啊,然后就开始各种天意难违和突发事件,总之就是男主经历的一周目全都屁用没有,唯一的作用就是用恶心死了的一周目全员傻逼神人剧情恶心死观众,那他妈的为什么不一开始就让男主的选择可以导致不同的结局,就是为了所谓的一百个结局和穿越这个噱头吗,有屁用啊 游戏本质就是一个两个不入流编剧带着一群更不入流的垃圾编剧写出来的一坨纯属是自我狂欢自我意淫自我感动的究极巨💩,小高和刚到底是被谁夺舍了才能写出弹丸论破1 2这样的故事,到底是什么样的究极傻逼才能写出百日战纪这种超级烂💩,抛弃一切逻辑和人物塑造就是为了整一个自我感觉良好的超级烂💩到底是他吗为了什么
Honestly best game every considering how many possible routes there are. Battles are challenging but also very fun. This game will take hours for me to 100% but that's okay since I love games that take time.
とりあえず主要なルートはクリアしました。 ダンガンロンパシリーズに限らず、ストーリー重視のゲームは大好物なので今作も非常に楽しめました。 SRPG部分や探索部分がいらんなぁ~という気持ちは非常あったものの、ゲーム性とストーリー性の両立の難しさなんだろうなぁと共感してしまう部分でもあります。 結果として、登場人物は全員好きになれたし、エンディングもいっぱいあるので、小高氏の言うとおり自分が気に入ったエンディングを自分の真エンドにしてしまえばいいので、改善点は色々ありつつも良いゲームでしたという感想。 ただ、個人的には「真相」的なものがあると、さっさと明かして欲しくてそこに至るまでの過程がどーでもいいと感じるくらいにせっかちになってしまうところがあるので、100日は長い!と感じてしまいました。 50日くらいでいい。 …いや、1日の密度を濃くして、30日にしてください。ちょうど一ヶ月でいいじゃないですか。 DLC出すなら買います。
真是一个垃圾的不行的游戏,剧情又垃圾又神人,主打一个想怎么写就怎么写。战斗更是一坨狗屎,一模一样的战斗打一万遍。
DEMO60点,1周目80点,想定2周目60点,全クリ40点 想定2周目までやる分にはそれなりのクオリティ担保されているが,その他のクオリティにムラがあり,総じて低い 攻略見つつ2周目やるならお勧めだが,全クリ目指す人はやらない方がいい 100ルートは水1Lにカルピス1滴たらしたぐらい無味
...so it's just cringe this whole time? always has been. no seriously you need help if you think anything from this game other than the over the top styling is good. dialogues? ♥♥♥♥♥♥♥♥ cringe. SLG tactical combat? barebones af. VN game design? holy railroad train wreck. 6/10
无聊且弱智,小学生剧情,一眼都猜得出来要写成什么样结果还要按头打100天忍受无数垃圾时间,人物脸谱化,战斗也很累赘,时不时强行降低所有人智商推进剧情,只能说失望透顶。
