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!

通关一年多了来补个评价 开卖前被小高吹上天,加上在平台的各种抽象宣传第一时间预购了。 实际游玩体验太失望。战斗系统无趣,剧情一半时间在水。不是很想支持百日战纪。 希望小高今年2x2能整点活,就算是v3那种烂活也比百日这种没活的来的好。
整体只能达到及格水平,非常标准的商业化作品。有时候节奏会显得有点拖拉。二周目的时候把苍月刀了的话,队友全会变成牛鬼蛇神,而且有些结局很莫名其妙,总之只能给一个臭中杯的评价。
幹你小高 我被迫目睹同伴不停死亡 但完成真結局是真的爽
目前二周目只通了四条线 [spoiler] (杀苍月的四条) [/spoiler]。整体体验还算不错,一周目剧情紧凑,人设表达良好,每个人的特征都十分明显,非常有弹丸味,对主线的把控也十分到位,也没有特别离谱的难以接受的问题;但二周目问题就很明显了,各种奇怪的选择,无法让人预判的走向,非常无语的100天睡80天,剧情也只能探出一点点,不少人设也崩塌,实在是令人失望。 音乐与美术其实与弹丸论破v3属于一个风格,可以接受,声优也恰到好处。对于战旗玩法可以选择一周目全打,二周目挂补丁跳过。 补充:玩完二周目真相大白线之后一切都释怀了,建议所有二周目都请直接玩真相大白线~
感觉玩完100个结局的我干什么都会成功的,真的是被小高和刚调成m了[spoiler] 谁懂游戏时长包含了多少昏迷般睡眠时间,点推荐纯属想陷害愁人 [/spoiler] SF篇乍一看伏笔回收满满(前置都是大粪结局篇啊啊啊啊啊),实则和真相大白篇左右脑互搏令人忍俊不禁,更有喜剧篇诺莫科巴篇等超绝水天数无敌重复动画,最敷衍连续防卫篇更是大份便餐任去一字肌肉记忆连敌方哪天尿哪里都记得一清二楚(绝望)[spoiler] 致敬三观最正最健康最不药物依赖主角最不出卖身体的领袖魅力篇 [/spoiler]
스토리도 흥미진진하고 루트도 많아서 각 루트를 즐기는 맛이 아주 좋습니다. 게임 시스템도 아주 재밌고요. 다만 엔딩이 100개나 되는 만큼 그 중에는 미연시 루트나 데스 게임 루트, 소년 만화 루트 같이 아예 장르가 달라지는 루트들이나 불쾌할 수도 있는 배드 엔딩도 있다는 걸 감안해야 하고 모든 떡밥이 풀리는 진 엔딩을 보려면 필수로 몇몇 엔딩을 봐야 해서 진 엔딩을 목표로 하게 되면 플레이 시간이 상당히 길어집니다. 전투는 스킵이 되는데 스토리는 안돼서 봤던 거 또 보는 느낌이 들기도 하고요. 가볍게 즐길 수 있는 게임을 원하는 분들은 아예 안 하거나 1회차만 하는 것을 추천드립니다. 1회차 엔딩도 열린 결말이라고 생각하면 여운 있는 괜찮은 엔딩이에요.
Let's go, in and out, 100 days adventure.
Amazing game with a lot of branching to explore!
pretty good
我不知道这个游戏后面怎么样,但我现在玩了15-20个小时左右,真的是太无聊了,剧情跟白开水一样,全是巨俗套无比的人设和剧情,这人设倒是没啥,剧情完全没有什么爆点,真的很奇怪,这厂其他游戏我都是从小玩到大,从PSP开始玩,甚至前两年较冷门的死神幽灵小侦探我也玩了感觉都不错或者还可以,但这游戏真的是玩的我目前阶段巨无聊无比,剧情节奏和以前玩半个小时就出爆点的老传统节奏完全不同,真的就是一直白开水,过家家一样,这前期剧情节奏设计的真有问题吧,真的得硬逼着自己玩,因为相信这个厂的实力,强行逼着自己玩,真是历代第一次,但即便我后续改好评,我感觉这游戏前期剧情节奏也很有问题,还有就是这个战斗,也太耗时了吧,感觉每次起码都得10分钟起步,问题我压根不是奔着战斗来的啊,对我反而是扣分点,我真的只想看剧情
