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!

很显然,又吃了一口小高喂的答辩,我很少会给游戏打差评,只是这次确实没忍住。抛开游戏剧情逻辑性不谈,整个战旗系统玩到后面简直便秘。最最最重要的是,实在是太TM催眠了,你们懂明明是睡醒状态却玩了几个小时后又困到不行吗?口口声声说不希望吃弹丸论破的老底,但我看出来了,你是做不出来和弹丸论破不沾边的游戏了,把推理系统改成战旗系统是不是就觉得自己不是弹丸论破V4特别版了。这次更是带着打越钢太郎一起被骂,还是那句话,点的低分外卖不好吃,也要含着泪给吃完,因为我是花了钱的。真相大白篇我知道你是想玩反战那一套,可是逻辑上根本吃不通,别说煽情和惋惜了,我直接三倍速跳着看,你依旧不知道玩家想要什么,什么超过一百多种结局,在我看来不过是营销的手段罢了,但你要问我弹丸论破2x2要不要买,我的答案是要的,因为这就是犯贱。
재밌습니다.

很复杂的一款游戏,在不剧透的情况下只能说是玩得周目越少感觉这个游戏可能就越好,不过如果一开始就对这类科幻末日题材不感兴趣还是不做推荐,游戏有多结局元素,尽量少看社区可以保留最大观感,虽然上面说玩得越少越好,但是真结局还是值得一玩的,也推荐在通过真结局后再看攻略选择其他结局。总体剧情有些爆点并且展开较为有意思,可以给到7分往上。 游戏玩法是战旗和文字游戏,战旗后期可以跳过并且升满级比较爽可以给一个高一点的评价。
스토리가 너무 궁금한데 전투가 뒤지게 재미없음. 이렇게 하품이 많이 나오는 겜은 처음임.
헌라 많이 사주세요
一周目玩完是干劲满满的,二周目是完全懵逼的,不知道问候了小高的🐎多少次,但玩完又原谅了。绝大部分的线都要求强行过完一百天导致不少地方都强行水,还有祖传早晚铃,严重消磨耐心,鬼知道我怎么忍到第66个结局才玩到真相大白篇的。但超大杯内容塞了各个角色ooc还有恋爱篇很大程度丰富了人物形象,怠宫真的是好女孩吧小高你是会做地雷妹的,[strike] 还有这维希涅斯也是个大情种啊,游戏里战斗打打架就算了打完架谁不想和老阿姨私奔呢 [/strike] [spoiler] 以诺维科夫自洽原则作为设定的SF线 [/spoiler]也挺有意思 [spoiler] 最先玩的就是死亡游戏篇,后面看到强行给伊娃洗脑真的让我难以接受,各种擦边黄段子也都笑不出声, 满脑子都是她和佳缪的故事,感觉身心都受到究极羞辱,心疼得不行。伊娃篇能看到她幸福是为数不多的治愈了,最喜欢的结局之一,反观那个SF篇全员存活真的就是强行包饺子了,纯纯绑架伊娃到地球啊意难平 [/spoiler]
很想给差评,但打完了真结局舍不得 这个语言的玩家在剧情中应该既视感很强烈 若节奏加快50% 小高哥哥的这个作品应该评价更高
sumino takumi
A história desse jogo parece que foi feita por um crackudo e eu adoro ela por isso
플탐 130시간 중에 80시간 정도는 그냥저냥 할 만한데 반복 플레이에서 오는 지루함+편의성 부족 때문에 50시간 정도는 지옥 같음.. 그나마 평 괜찮은 루트만 골라먹으면 못 먹을 정도는 아닌데 올클은 도저히 추천 못 하겠다.... 그거랑 별개로 공식 한글화는 감사합니다
