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): 0/day in the week to Sep 1 → 0.43/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 2,402 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.

小时候iOS商店上卖18块钱,磕磕绊绊没有玩完,现在steam上补票通关了,而且全成就也不难。鬼子僵尸还有晚上岛上环境看着太吓人了当时的我只敢开最低模式玩。废弃营地、海岛密林,还有一根根特斯拉电棒氛围感十足。前期发育一波以后,在后期生存基本没压力了。但游戏毕竟年头久了,优化也一般,手感不是非常流畅
好游戏,就是优化比较差,画质也是停留在十年前
Audio Bug 💔

Buen juego está entretenido, me trae recuerdos cuando lo jugaba en teléfono
只论内容,不算特别丰富,但考虑到37元的价格,以及超低的配置要求,那是真的出色
интересная игрушка, в которой было довольно весело проводить время, игра не напряжная и довольно простая)
Principalmente me lo compre para revivir esa nostalgia de cuando lo jugue de mas chico en mi celular pero vaya que a pesar que ya tiene sus años y todo el juego considero que aun es bastante bueno, si nunca lo llegaste a jugar y si tu pc no es muy nueva la vdd sies una buena opcion
Hat mir tatsächlich Spaß gemacht...!!!
good
extremamente datado, porém, extremamente divertido, ótimas horas de gameplay, gostaria que tivesse acesso à oficina.
