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!

是非購入することをオススメします!......ですが、引き際を間違えない方がいい、とだけ言っておきましょう。 このゲームは、所謂マルチエンディング型のゲームです。 プレイヤーの選択によってストーリーが多様に分岐するのですが、その数なんと100! ただ......当然と言えば当然ですが、全てのルートを同じシナリオライターが書いているわけではありません。 なので、ライターによってキャラの台詞や行動に大きなブレが生じている場合がございます。 私はストーリーの精巧度、完成度はもちろん、キャラクターの魅力を重視するのですが(誰でもそうでしょうけど......)、自分の好きなキャラが絶対にしないような行動を取られると少し冷めてしまうんですよね...... 「あれ、これシナリオライター間でキャラクターの解像度が統一できてなくね?」みたいな感想が頭をよぎります。 いや、ぶっちゃけ言うとよぎるだけじゃないですね。 私は、「推理編」をプレイしている際、息苦しさすら感じたのです。 「真相解明編」をクリアした時の興奮と心臓が苦しくなるような切なさをぶっ壊され、ぐちゃぐちゃにかき乱されたかのような不快感を感じました。 「このゲーム、大好き!」、「神ゲー!」といったポジティブな感想が途端に色を失ってしまうような......いや、この程度で色を失うなら、元々そんなに好きじゃないのか?うーん、それも違います。 紛れもなく、私はこのゲームが大好きですし、オススメします。 ただ、最初に言ったとおり、引き際を間違えないようにしましょう。 最初の数日間でキャラの台詞がおかしくね?と違和感を感じた場合は、即座に別ルートに切り替えてください。 それが読後感を守り、あなたの心を守ることに繋がります。 「100ルート!?全部やってやらぁ!」なんて思考は今すぐに捨ててください。 自分の好きだと思うルートだけプレイする。それだけでいいのです。 あるいは友人やネットの意見を見て、参考にしてください。 そうすれば、あなたにとってこのゲームは神ゲーであり続けます。 もう一度言います。 引き際を間違えないでください。
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
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.
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
...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
гoвнo
虽然全通至今已经过了半年多了不过还是来写个好评。没赤过石的可以来吃,量大管饱保证有最对电波的路线和最难忘的史线(贬义),二周目最初不锁线就极不合理,小高和刚自己打过没就端出来这个?看攻略走真相线可以获得不错的游戏体验,至于初见就进上半区的我只能说孩子你有福了。如果有异食癖说不定在一些玩家公认的“史线”里也能品出巧克力味,虽然写到现在都在骂但我个人还是很喜欢这游戏的,跟小高和刚自己写的几条路线对上电波的话就会像我一样半年多了还在被这破游戏套牢,不过小高以后能不能别和打越合作了你俩根本尿不到一个壶里。
This game has Darumi in it
I was extremely hesitant to buy this game, It just didn't seem like my kind of game but after playing it *the main game, i haven't done any of the 100 endings yet but i will* I am pleased to say this was fantastic and had me engrossed in the story and characters the whole time. Sure it has some problems like the UI and map can be kind of bad at times and this one minigame is kind of boring after awhile, but the combat is fun. i might update it after the 100 endings if i still have sanity left, i just hope they are unique enough being so many.
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。
