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 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.

I don't know why this game has a review score as low as it does. Sure, it's not as good as Plants vs. Zombies, but I think it's a great game. There's a lot of variety in the types of martians and in the defenses, and you have a zapper gun that you can use to inflict extra damage and do various other things. You'll be using it a ton, basically. The spring and summer levels can be a bit slow, but things really pick up in fall and winter and can get pretty challenging at times. There are also themed bonus levels and several challenge levels, all of which I thought were great. Overall a fantastic game, really enjoyed it.
muy bueno, el modo normal es bueno para aprender las mecánicas, el modo veterano da mucha dificultad, me encanta, odio el modo veterano, pero es un odio sano

This is a simple, by the numbers little tower defense game. It has a vibe similar to the old Plants vs Zombies, but with more traditional tower defense mechanics. The base difficulty is fairly easy, but starts to spike quickly in the second half of the game. The number of allied units is kept relatively small, which keeps things simple. There isn't a huge variety of enemy units, but each is different enough to be meaningful. The mechanics generally cleave closely to the genre, but there are a couple novel elements introduced. The main places it differs from typical tower defense are: 1.) You gain no points from killing enemies. All currency comes from economic towers you build. 2.) Rather than having a base with health, you instead have a number of cows that the martians attempt to kidnap. They have to both reach the cows and return to the spawn point with them, giving you around twice as much track to fight them off. 3.) There are various tools you need to actively click to use, including a captured martian raygun or a cowbell to encourage captured (and then escaped) cows to run back to their pen faster. You also have to manually collect currency from your towers. So overall, it's a bit of a different experience, but still solid tower defense gameplay. There's really no downsides here, except perhaps being a little on the simplified side. It's a great game to try out the tower defense genre, though tower defense veterans may want something with more variety or more depth.
Excellent jeux de défense de tour dans l'univers des vieux film d'invasion de martiens.
Es un tower defense bastante desafiante el cual te lanza algo nuevo cada vez que progresas en este, esta bastante bien balanceado y me agrada que es un TD que no solo tienes que estar mirando lo que hacen tus torres, tienes siempre que estar al pendiente de lo que esta pasando. Ojalá más personas conocieran este juego.

Full review: https://thegamehoard.com/2026/05/09/picking-up-steam-beware-planet-earth-pc/ Beware Planet Earth’s tower defense gameplay is decent but a bit unambitious, the towers, lane layouts, and aliens working well enough to provide levels that require some thought to overcome… at least until you factor in the Zapper. The little ray gun adds a layer of constant involvement yet comes with the drawback of it breaking down if used too much, but with levels designed around its constant use it goes from a tool to let you be more involved in taking out Martians to a bit of a nuisance. It doesn’t require much strategy to hold down the left mouse button and the gun’s presence clearly impacted how powerful individual towers were allowed to be, Beware Planet Earth not completely sacrificing tactical tower building but losing some of its focus in pursuing a rather plain form of active involvement.
Ідея прикольна реалізація середня. Це тавер дефенс який по сюжету по проходженню рівнів відкриває нові машини і челенджи, а гравцю необхідно не дати вкрасти інопланетянам своїх корів. Гра прикольна тим, що є лазер та колокольчик, з якими гравець активно взаємодіє, наприклад лазером знищуючи бульбашки невразливості у вчених. Колокольчик звісно рідко використовується але все ж. Мені подобається арт та концепт, різні вороги класні окрім [spoiler]моба, який знищує машини гравця, він занадто жирний ще й ламає машини. Краще було б або зменшити дуже хп для лазеру або взагалі вирізати з гри[/spoiler]. Гра гарна на декілька вечорів чисто сюжет на ветерані. Челенджи та доп левели на ветерані погані - це трайхард ускладнений відсутністю хоткеїв. На жаль дуже багато машин є безкорисними або слабкими, ефективна стратегія втупу спамити всюду стартовою мащиною за 200. Дуже не вистачає хот кеїв або на машини, а краще на лазер та колокольчик, бо однією рукою у різні частини екрану перемикати це капець. Основний сюжет норм, я всю гру тільки на ветерані грав і рекомендую так робити. Прикольно обіграна тематичність рівнів, коли восени ростуть гриби які треба прижигати, а взимку замерзають машини. Але погано те, що всіма машинами особливо немає де користуватися - коли відкривається остання машина по суті завершується сюжет. Челенджи деякі прикольні деякі складні тупо через відсутність хоткеїв на лазер та машини. Бонусні рівні тематично прикольні, по геймплею погано, особливо рівні зі всесвітами Валвів типу халфи та тфки, я того Гордона Фрімена зненавидів. Взагалі не дуже сподобалось що після сюжетки доп рівні та челенджи це загатовлений вибір машин і ніяк інакше. Хотілось би просто більше стандартних рівнів де потрібно самому набирати машини та добувати шестерні. Сумно що гру далі не розвили по типу як першу частину ПвЗ, після проходження сюжету якої є багато чим ще зайнятися. Після повного проходження гри можу сказати що я ще б раз пограв у ній тільки в сюжет на ветерані. Або пішов пограв у першу частину PvZ.
