60 of 190 · most liked firstWhile I liked the cartoony gfx of the game, I was reluctant to play a TD where the tower are designed not to get the job done (yes, on purpose). And in the end this game was not for me. I get the fact that people are trying to reinvent the TD genre, but honestly, isn't designing a solid TD hard enough? Usually, when features are added the towers are left behind. Beware planet earth is a good example of this. Towers are lackluster and their range is minute. If you like frantically clicking in a…
negative · reviewer's own thumbsView post →This is a VERY GENERIC tower defense game, which is almost identicle to "Go Home Dinosaurs" You place down "income generators" and then use your money wisely to buy varios types of towers to defend your base. + Great art style + Challenging (on Veteran) + Humous levels / enemies + Easy to learn - Can not upgrade towers - No Abilities - No health bars on enemies - Very repetitive and slow paced - Story is lacking (basically martians are trying to get your cows...that's about it) - Level…
negative · reviewer's own thumbsView post →This game is both cute and has depth. It will appeal to casual players who want to see cute / funny things on the screen (think plants vs zombies crowd) and also to the players who want depth of strategy (think defence grid players). I have finally found a game that will appeal to both me and the girlfriend. Easy buy after playing the demo. Try it. I bet you'll like it. And don't let the laser gun turn you off, like it did me at first. I thought it was just a tedious laser to shoot stuff with…
positive · reviewer's own thumbsView post →No recommendation for this game. It's not that it's bad, it's just that it's another tower defense game that does nothing to distinguish it from any others. None of the towers feel like they have any weight behind them, everything is just really generic and boring. Fast+weak enemies, check. Slow+tough enemies, check. Regular peashooter towers, check. No damage slowing/freeze towers, check. It's a reskin of every tower defense game you've ever played. The current sale price of 2.74$ is barely…
negative · reviewer's own thumbsView post →People make comparisons to Plants vs Zombies. I'm only a couple hours in and found it frustrating. On Veteran Mode, your towers feel miniscule compared to the enemy hp pool. Winning on some level requires taking exactly the right towers. Towers are overall very boring, the first 5 you get (compared to Plants vs Zombies): Sunflower, Incredibly Weak PeaShooter, Frozen Pea Shooter, and then you get the two worst, a Bomb and a Landmine. I keep waiting to unlock good towers but the only ones I've…
negative · reviewer's own thumbsView post →Fun tower defense tower defense time waster, with cool graphics and cartoony 1950s aliens theme. However, get punishingly difficult once you hit Fall, to the point where its just not fun anymore. Even plants vs. zombies was fairer!! Buy if you want some decent fun for a few hours and then home work assignment thereafter.
positive · reviewer's own thumbsView post →it has everything I like! cows, aliens, lasers and a lot of fun! it starts to get really challenging the more you play, I just love it so much, best purchase of the month!
positive · reviewer's own thumbsView post →This game exceeds expectations. Tons of fun and a lot more challenging than I thought it would be. The cutesy cartoony design totally fooled me. Haha. Very addictive too.
positive · reviewer's own thumbsView post →It's a very good tower defense game. The cows made me laugh as soon as I got into the game. It is quirky and unique.
positive · reviewer's own thumbsView post →Byte-sized review Beware Generic Game Review in under a minute Generic tower defence game that was clearly trying to cash in on the Plants vs. Zombies craze but lacks the humour, progression and balance of the game it is trying to ape and what you are left with is a dull, boring slog that at times feels more like work than something you would actually have fun with thanks to a difficulty curve that feels unforgiving. There are hundreds of better tower defence games out there so why waste your…
negative · reviewer's own thumbsView post →Can't. Stop. Saving. Cows! This is totally not my type of game, but the demo was so entertaining that I just had to put it on my wishlist, and then get it when I saw it on sale for 1.99 euro. It's well worth more than that (and I'm stingy). The graphics and humour hits the right spot for me. It was great fun until I tried to get those stupid achievements, then it turned into frustrating no fun on the Veteran play through of Winter level 5. After far too many attempts on the previous levels…
positive · reviewer's own thumbsView post →If you like plants vs zombies then you will like this 2-D game
positive · reviewer's own thumbsView post →A very run-of-the-mill tower defence game. Not much variety in towers or enemies, and the game failed to grab me in any way. It's not awful, but there are many better games of this genre out there eg the similarly-styled Dinosaurs Go Home, or Defense Grid, Space Run, Plants vs Zombies etc.
negative · reviewer's own thumbsView post →Painfully addicitive tower defense in a playful enough package to keep me coming back. Hints of Plants vs Zombies, but stands on it's own quite well. Kept me coming back and well worth the time. Challenging enough to make the effort to get 100 percent completion and I strongly suggest you do.
positive · reviewer's own thumbsView post →TL;DR: Rather simple cartoonish inoffensive tower defense game. Martians are coming and you must use a bunch of mechanical contraptions (fridges, grills, ...) to stop them from abducting the cows. I've played this game for about 14 zones in Veteran mode (Summer, invasion 4). BPE takes some cues from Plants vs Zombies: having to click currency icons to collect them (cogs in BPE), cartoonish visual style with rather silly enemies (Martian maids, crazy scientists, ninjas, ...), pre-mission…
negative · reviewer's own thumbsView post →Cutest game ever! <3 20/10
positive · reviewer's own thumbsView post →If you like PvZ do yourself a favor and try the demo at least. This game is fun
positive · reviewer's own thumbsView post →If you're a PvZ fan then you'll definitely like this game. This game requires much more planning and strategy, and it has a Veteran mode which is quite unforgiving. I will point out I experienced some glitches in the game. For instance there's a problem where intermittently the game won't allow you to pick up the zapper, cowbell, and the detonator. And sometimes it freezes when you exit full screen. Overall, give it a go. The pros definitely outweigh the cons.
positive · reviewer's own thumbsView post →A very well done PvZ variant/clone. Fun characters and descriptions, fantastic art, and can get quite challenging!
positive · reviewer's own thumbsView post →It has a Plants vs Zombies type of feel. The gameplay is pretty much the same, but.. its not zombies, IT'S ALIENS!!!! Makes the game completely different *snort*. I give it a 7/10 aliens
positive · reviewer's own thumbsView post →Now here's a curious one: a Tower Defense actually published by Bandai Namco. It's just about the only indie thing in their catalogue from what I can tell, too. Surely the game must be pretty good if that's the case, right? Well, I'd say no sadly. Like some other games Beware Planet Earth has you fighting aliens, in this case 50s-era little green men coming to abduct your cows - well, someone else's cows, but you're being a nice guy and helping them with that while he's stuck in the outhouse.…
negative · reviewer's own thumbsView post →Fun if not terribly original or complex tower defense - but don't we play TD because we know exactly what we are getting?
positive · reviewer's own thumbsView post →This is more of a action/tower defense as you get a cow bell to make the cows run faster back home, and a laser used to directly hurt aliens, unfreeze defense, or destory shields (among other things). Alians do variaty of things, make portals, rocket jump, destory your defense, shields, and play music. You must be active thoughout the whole battle to keep the alians from taking your cows to do unspeakable things. The added challange modes and the TF2 and zombie maps were fun change of pace.…
positive · reviewer's own thumbsView post →great game, not my first time playing this game, probably third or fourth time playing it. definitely recommend to try it. but i have a problem with beating this game completely in veteran mode because for me this is absurd, the game itself sometimes feels quite tough, specially on challenges and bonus levels, not even talking about story mode where you have to replay 46 levels again. me beefing with achievements actually.

unlabelledView post →I really don't like this game. I wanted to. I love tower defense. I don't like this. This is the mad-clicky sort of tower defense, and it doesn't even feel slightly strategic. The only positive I can offer is that the game is pretty difficult in the later stages.
negative · reviewer's own thumbsView post →Plain tower defense with 0 (zero) upgradeability, gets boring real quick.
negative · reviewer's own thumbsView post →Very simple and relatively hard tower defense game with cute graphics, but otherwise clearly made with a very low budget. It basically tries to steal Plants vs Zombies' jokes and style, but lacks everything that made PvZ a great and very addictive game (like the flawless presentation, sense of progress, meaningful difference between the various 'towers', excellent balancing, perfect user interface, and so on). There are so many excellent tower defense games on PC, some more traditional, others…
negative · reviewer's own thumbsView post →Nothing wrong with this game, but there's nothing about it that warrants playing it over the hundreds of free tower defense games on the Internet.
negative · reviewer's own thumbsView post →Silly game with nice sense of humour. If you want to kill time, go ahead.
positive · reviewer's own thumbsView post →This is just an initial review for how far I've got with Beware Planet Earth. Beware Planet Earth is a strategy type game with very similar to themes to Plants vs Zombies. Its different in the sense of rather than having enemies come down lanes you have a pathway, later levels can be more pathways that lead to the same thing which is that at the end of the path are some cows (moo) you have to make sure the aliens don't steal your cows in which they have to get all the way to the cows and then…
negative · reviewer's own thumbsView post →A rather uninspired clone of Plants vs. Zombies, emphasizing action rather than strategy. The pace becomes quite hectic in later levels, even in easy mode (playing in veteran mode becomes ridicolously hard in the third season at the latest), since you constantly have to click various objects and enemies with the Zapper gun. Selecting and placing turrets and refining your strategy becomes a minor matter then, also due to the fact that the turrets themselves are rather boring (single target…

positive · reviewer's own thumbsView post →It appears deceptively easy at first, but gets harder pretty quickly. Quite a bit of direct involvement in battling Martians, not just setting up towers.
positive · reviewer's own thumbsView post →Poor mans plants vs zombies. Also very unbalanced game for how tiny levels are compared to creep spawning rate.
negative · reviewer's own thumbsView post →This game is no fun and is pure work, especially on Veteran difficulty. The whole difficulty is not in finding the right tactics, but in clicking 2000 things at once while keeping an eye on your Zapper's cooldown. In other words - it's pure mechanical, not strategical. Nice graphics/animations and similarities with Plants vs Zombies doesn't save this game from being a dreadful experience. No speed toggle is another issue, especially at the beginning of levels. No resolution options -…
negative · reviewer's own thumbsView post →This game is horrible. Pros - the graphical style, but just to trick you - music Cons - no 1080p resolution, really - you find better games online for free - too much text, very annoying if you restart a level, explains the same thing over and over - veteran mode ? , can't even finish on normal - the absolute uselessness of towers and so much multitasking it ruins the fun, too much work - overwhelming waves of enemies that are also having too many advantages, and no time and enough resources…
negative · reviewer's own thumbsView post →My kids love this game!
positive · reviewer's own thumbsView post →Very limited and oversimplified tower defense game. Not worth the $10 price tag imo. After the first ten levels gameplay just continues on the same. No innovation or real fun to be had here move on.
negative · reviewer's own thumbsView post →If you're going to clone Plants versus Zombies at least throw in some tower defense. Beware Planet Earth is the most basic, simple, straightforward, uninspired, copycat, utterly tedious game on Steam. It's not really a tower defense game because the levels are puzzles (if you can call iGame obviousness with almost no failure possible a "puzzle"). Be prepared to sit and watch in boredom as aliens march across the screen and you hear PVZ "splot" noises and spawn noises the developers made with…
negative · reviewer's own thumbsView post →completely unremarkable tower defense game.
negative · reviewer's own thumbsView post →If you like casual Tower Defense games like Plants vs Zombies, you might also enjoy Beware Planet Earth. It's a very simple TD game, where you slowly build up your armoury but only have a limited amount of slots for your towers, factories, mines etc. and have to decide which items to based on a preview of the enemies you are going to encounter. Polished like a high-end mobile game, I can't really find any faults other than having seen this type of game a thousand times before.
positive · reviewer's own thumbsView post →6/10 I'm recommending this, but barely. While it is creative and somewhat fun, there's far less emphasis on strategy than in most tower defense games. There are many times when the determining factor on whether you beat a mission is almost purely luck. You might have to play the same map several times, until you get lucky in the way things turn out.
positive · reviewer's own thumbsView post →This game is amazing!
positive · reviewer's own thumbsView post →Let's get one thing clear: This is a Plants Vs. Zombies rip-off. The second thing to make clear is that this game has the worst music I have ever heard in a videogame, going all the way back to the Commodore 64 era. Seriously, it is so astonishingly awful that I doubt anyone will make it ten minutes without shutting it off and leaving it there. Now the good news: this game is actually well-balanced and pretty fun. The levels are challenging but not impossible in standard mode (veteran mode…
positive · reviewer's own thumbsView post →Good points on music and graphism, for a strategy challenge, not that easy on top of the Veteran Mode that makes this game hard. If the first levels are quite cool, the leveling offers new challenges and interactive action with the Laser and the money earning system. A really cool tower defense in my opinion.
positive · reviewer's own thumbsView post →Beware Planet Earth is a fun TD kind of like Plants vs Zombies. Some levels are really tough and you have to use a lot of strategy. There are several different kinds of towers and traps to choose from and many different kinds of aliens. Good fun!
positive · reviewer's own thumbsView post →I old game but very fun! Clear inspiration from Plants Vs Zombies, but brings a new twist!
positive · reviewer's own thumbsView post →I realised I have 1100+ games in my Steam library and I was going to die before I played them all. So thought I'd spend a bit of time on each one, a new one every night, and leave a short initial review. I LOVE THIS! I am a Plant Versus Zombies veteran, (1st one, not the horrible monetised versions that followed) and this reminds me massively of the zen fun I had with that game. Similar tower defence concept, cute graphics, cute game play, cute music. I hope it plays on my Steam Deck with…
positive · reviewer's own thumbsView post →Not Plants vs. Zombies but Cows vs. Aliens! Absolutely love this tower defense game.
positive · reviewer's own thumbsView post →It's cute, it's funny at times, but it's insanely repetitive. Also the game is really inexplicit in its wording almost all the time. "More damage".. okay.. but how much more? Tower Defense games are all about maximizing your defenses and this attitude is not viable in my opinion.
negative · reviewer's own thumbsView post →Beware Planet Earth is a neat little tower defense game. It's not particularly difficult, and it wears it's Legally Distinct from Flora vs. Undead themes on its sleeves. This definitely feels like a mobile port, but it ran fine in either case.
positive · reviewer's own thumbsView post →Good tower defense games are usually addictive and you can spend many hours in them. This one is rather for shorter sessions because the game concept is more based on time management than strategic planning. The pros are sense of humor, short levels, variability of enemies and easy control. The cons are action rather than strategic gameplay, steep difficulty curve, low variability of defense structures without possibility to upgrade and the game become repetitive after some time. Pros: -…
positive · reviewer's own thumbsView post →If you love the genre, this is a solid addition to it. Personally, I don't play these types of games often, so when I do I'd rather play the Fieldrunner series, or Plants vs Zombies. Game's not bad though, works ok with touch screen computers, but the resolution is low, and cannot be adjusted. So when using touch screen sometimes it doesn't click in the exact right place. When I do play this sort of games it's usually on my Surface Pro 2, so the quirkiness of the touch controls is a big part…
positive · reviewer's own thumbsView post →I think I paid for this game. I liked it. Nice action tower defense game, with cows. Would have paid if I hadn't. I'd say a 7. Nothing very exiciting. Decent in every way.
positive · reviewer's own thumbsView post →This is a tablet/mobile game ported (badly) to PC. While the game is stable, the resolution cannot be changed, and it doesn't have widescreen support - it's pillarboxed. A sloppy and lazy technical implementation - they ported it to PC just to try make a quick buck. Gameplay is just Plants vs Zombies - it's a ripoff with what would be a tolerable theme if they hadn't tried to treat PC gamers like imbeciles. Thumbs down for treating PC gamers like idiots and shovelling tablet games onto…
negative · reviewer's own thumbsView post →i got this game in a humble bundle and so did not pay full price. I enjoyed my time playing beware planet Earth. It's a fairly standard tower defence game but it does justice to its genre. The main twist (in lack of a better word) of this game is that as well as letting your towers kill the aliens you also have a laser that the player controls which must be use tactically to avoid overheating, It adds a degree of control to the player that you don't see in most tower defence games. There are a…
positive · reviewer's own thumbsView post →This starts out as a solid yet typical tower defense game. The game really begins to shine when the gun becomes a primary element that performs many different gameplay functions. Having this 3rd major element to compliment the standard towers and resource management makes this one of the most hectic and action based TD games in the genre. Fantastic presentation, solid level design, unique enemy units, fun themes and great bonus levels make this a great package for fans of the genre. GG!
positive · reviewer's own thumbsView post →One of the best tower defenses on steam.
positive · reviewer's own thumbsView post →Unlike other Tower Defense games has been seen on internet etc. Art style looks pretty good, like Plants VS Zombies, but different developer. I never been familiar a kind of game since, but I like it! Even the Martians roles as Valve’s characters....also features a Memes content as well, Gentlemen....
