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!

简单总结一下就是小高神了,打越拉了。小高负责的游戏一周目和真相大白线及相关支线体验都很好,除了些许恶趣味支线以及连续防卫篇,游玩过程中无疑可以带动起感情,人物塑造立体。而打越主笔的SF线,虽然给出了一堆设定,什么平行跳跃之类的,确实很有趣,但这条线的故事着实让人提不起劲,人物塑造单薄,特防队全部人对事情的真相避而不谈,甚至知道siri会洗脑技术后也没有任何疑问,就仿佛全部人都被提前洗脑过了成为特防队全bot一样,对比之下那些粪支线,比如鲜血淋漓,死亡游戏,灾厄之匣之类的虽然个别人物OOC剧情推动稍显僵硬,但是人物塑造无疑是在线的,人物的一举一动以及情感波动都能让人带入到故事当中,偏偏就打越负责的sf线以及推理无疑是拉完了,人物塑造和故事一个不成立,推理篇的两个凶手更是让我怀疑是不是本人,和其他路线完全不一样,纯为了时空循环包了一叠饺子醋,而且这个设定还和小高的真相大白路线有些许冲突,完全可以看作另一个世界了都。另外,全篇唯一要说的通病就是有些时候太水了,自由活动一水就是好几天一点有效剧情都没有,特别点名幸运之匣篇,四个大100天愣是一天不跳,让玩家赤完全程的自由活动和大富翁,甚至剧情都没有太大的变化,对比之下同样分出四条分歧的喜剧篇无论是剧情变化还是有趣程度都远远高出它。百日战记无疑是个好游戏,我也推荐大家游玩,但建议大家玩二周目大部分路线的时候,就当是一个全员参与的番外tv来看吧,这样无疑接受程度要高不少,而想要一周目刚过的玩家,想要强剧情体验,我推荐直接进真相大白路线及其相关支线就好了,千万不要进那些无关支线,不然的话一周目积累的情感很可能会消失不见,
你是谁?请支持百日战纪!

I don't know what to say actually. Overall, game is good. I liked it. But I think it could have been better on some matters. Still, I'll give it a solid 8/10. Recommended on discount!
I love this game. The gameplay is split (rough % for each part) between Visual Novel storytelling with choices of how to spend your time (79%), grid based tactical combat (20%), and a mostly boring board game like map (1%). If you really don't like visual novels or story in games this is nor for you but if you're here for story and occasional tactics then I'm sure you'll enjoy it. Very strong Danganronpa energy for obvious reasons. Ran great on Steam Deck. Will easily last you 100 hours.

Absolute banger. Highly recommend if you're into stuff like Danganronpa, Zero Escape or Ai: the Somnium Files. It's incredibly long with a cool, unique story.
Gameplay to w większości Visual Novelka jak inne ale niech to cię nie zwiedzie. Fabuła jest niezwykle rozbudowana i wciągająca, postacie są dobrze napisane, dają się polubić oraz zachowują się spójnie w większości scenariuszy. Tajemnice trzymają w napięciu a rozwiązanie zagadki jest satysfakcjonująca. Protagonista jest dobrze nakreślony mimo wyborów które niekiedy kłucą się z logiką tej postaci ale to juz kwestia tak rozbudowanej fabuły która niekiedy ma dziwne rozwiązania. Wiekszość scenariuszy jest unikalna ale zdażają się skopiowane dialogi sceny 1:1 z innego. Głównym daniem gry Gameplayowym są obrony Szkoły. Bitwy toczą się turowo gdzie mamy określoną ilość ruchów. Każda postać ma unikalne umiejetności, sposób poruszania się przypominające figury szachowe. Umiejetności mozemy ulepszac w ,, czasie wolnym,, w dniach miedzy bitwami. Są jeszcze ekspedycje poza szkołę gdzie zbieramy zasoby które możemy wykorzystać na wytworzenie prezentów lub ulepszenie pułapek i mikstur. 1 Scenariusz jest w 100% liniowy, lecz przy 2 podejsciu zaczyna się prawdziwa uczta. Sami mozemy sobie podejmować wybory które mają konsekwencje niekiedy jest to zrobione dziwne ale przez wiekszość czasu działa. Zakończeń jest oczywiscie 100 - dwie są najbardziej ciekawe odnośnie rozważań o ten jeden kanoniczny ale subiektywnie można sobie wybrać ten który najbardziej ci pasuje. Ogólnie gra bardzo fajna polecam sobie sprawdzić.
i love meta narratives, and despite the game not being too complex mechanically and needing a while to get the action going it was so worth it. Despite the game having like a 100 endings I think it's best to go in expecting to do 2 playthroughs, and go for more if u really get attached. The "main" 2 endings are where the game shines it's brightest, but there are other notably good ones (among other dumpster fire endings).
This is a generational game
