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): 0.14/day in the week to Aug 25 → 0/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 2,400 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.

Za mě to je jedna z nejlepších, ne-li nejlepší TD hra...a to jsem jich moc nehrál
I absolutely do NOT recommend this ♥♥♥♥♥♥♥♥ game, I got all achievements and I only have this many hours because of SAID achievements. What made this experience so terrible you may ask? Well, not only was I mind-numbingly trying to get the achievements, the stupid music score playing NONSTOP REPEAT and having to listen to my NOW EX HATE ME DURING OUR RELATIONSHIP BECAUSE I WAS ♥♥♥♥♥♥♥ PLAYING THIS STUPID ♥♥♥♥ AND NOT GIVING HER ATTENTION And by golly this did NOT make the experience anymore fun. I do believe this game had a hand in ending my relationship. Maybe, I am the problem. But maybe it isnt the break ups that truly matter but a break up of plaque and harmful bacteria is what truly matters in living life. fk this game bro.

[h1]¡Defiende Esa Amígdala!: Una Aventura de defensa y bacteria en \Defend Your Life\[/h1] [h2]Resumen[/h2] Si alguna vez soñaste con convertirte en guardián de tu propia corriente sanguínea, presta atención. ¡\Defend Your Life\ es tu oportunidad de brillar! Administra defensas más hábilmente que tu propio sistema inmune en un día malo de gripe. Cogiendo al libro de ciencias básicas le añaden caniones, ¡porque todos sabemos que eso es lo único que les faltaba! [h2]Aspectos importantes e interesantes[/h2] Imagina por un momento que eres un superhéroe microscópico, pero en lugar de salvar la ciudad, tu misión es proteger arterias y apéndices. \Defend Your Life\ mezcla estrategia con un toque de humor porque, ¿quién no se ha reído alguna vez de un buen chiste sobre células T? El juego te permite conocer y manejar aspectos básicos de tu cuerpo, pero de una forma que definitivamente no viste en clase de biología. Además, ¡quién necesita realismo cuando tienes células con sombreros! [h2]Aspectos por Mejorar[/h2] Aunque la premisa es tan fresca como una visita al médico, en algunos aspectos, parece que ese médico todavía está usando un pager. El juego podría mejorar en variedad de enemigos y escenarios, a veces lo único que cambia es la magnitud de la amenaza bacteriana. Además, las voces podrían usar un poco más de entusiasma —las células podrían sonar menos como que están dictando un seminario de bioquímica y más como que están en la batalla mítica por la supervivencia que realmente es.

Aunque hay áreas de mejora, esta travesía celular tiene suficiente chispa como para merecer un espacio en tu colección, pero tal vez espera a que lo encuentres de oferta. ¡Compralo con descuento! Esperamos que con esta guía estés un poco más cerca de decidir si quieres tomar las riendas de tu propio sistema inmunológico. ¡Recuerda, las células no van a defenderse solas!
It's a good tower-defense game, but could have been better... Recommended, especially if it's on sale!
Fun and simple, but not eay, TD game. Does nothing new really, but like Kingdom Rush series, it does TD well. Use currency collected during play to upgrade towers and powers. Get heroes and upgrade them. All while trying to defend your life! So if you like TD games I would recommend this.
В своё время, помнится, играл. Не знаю почему, но запомнилось прям. Вполне неплохо, но не более того.
