UPDATE GAME SO we CAN PLAY IT ON MY IPAD.
This was our favorite game. Now we cant play no more. Very sad. Please update.
We used to play this for hours, itd would get boring, but then Id always come back. But one time we came back and it said we couldnt play because we had to high of a IOS version. Can you please update the game for IOS 13.
We have play this when it started when the new IOS update we couldnt play it no more. But this game was our favorite we would always play this game for hours. This game also has everything we needed, the graphics is amazing, certainly one of the best but, pls update a game. Pls pls update.
This is one of the best tower defense games Ive played so far and we really want it to be updated so we can play again. And we still have it downloaded even though we cant play.
Please update! Best td game ever.
Hey, just wondering if you could possibly update this game for IOS 11.
This is a great game and the levels are amazing. Some are harden than others but the challenge is great. Every level has its own strategy to it that you need to figure out to win. Overall great game.
We love this game! We've beaten every level and it's still fun to play. BUT it's time to release a new version or more levels.
This game will make you think and strategize. We have completed all the levels twice now so it is possible to beat each level. Great game to keep you busy and entertained.
Great tower defense game.Need more new weapons and upgrades.
The game so cool you guys should make a new update and more and we bet players like would get the so thank you for reading this Nina kiwi and we hope u guys add new tower bye.
This is a perfect (as perfect as a game could be). It doesn't have the easiness as other tower defense games. You can't just try once then complain how it's to op or whatever. It's a hard game, And people always play super easy TD games.So people get mad. However, people who like a challenge, this game is for you.
Not like many TD Games, very nice but its hard from the start! Dont like hard then get something else. Very challenging and you have to get a good strategy to succeed. We past a few levels ourselves and recommend it for people that can play hard or heavy risk games.
Love the game! It's a challenge to complete, but that's what makes it interesting.
The game is great but recently we've been unable to use our SAS dollars to unlock the 1000 barrel and electric fence. Please fix.
This is the best TD game we've ever played (which is saying a lot. . . We've played all of them, past present and future). It is more challenging to get into but keep plugging away! – it is 100% worth it when you start to get into the game. Enjoy.
We don't understand how people think this game is too hard because we actually beat the first level on our first try so it's not that hard! Love the game but the tank thing with them skeletons are WAY too over the top. Use all of your stuff on a boss and he's not even hardly hard.
We won't lie this game is hard-very hard and that's why is fun and unique. Every other tower defense game is WAY to easy. We have completed every level on this game on Nightmare difficulty if this game is to hard for you then play BalloonsTD. Our highest wave we're on is 837 and we're still doing that level it's possible if you try.
Just get 2 maxed out machine guns at the end and put 2 layers of titanium barricades, in our opinion it's be easy.
The game is kind of hard, but it is really fun. If you like tower defense games, this is a great game to have. You fend off hordes of zombies with turrets and soldiers. To us it is one of our favorite games ever.
Great game. Takes a few tries to work up a good strategy, and the higher levels take many more. If you take the time, you'll do well.
To the people crying about it's to hard… We something our wife likes that's really hard…. Try that and stop being a baby.
People think this game is hard but gets easy the more u play it u have to find strats that work for the different levels and difficulty.
We've seen people complaining about the difficulty of this game a lot. Yet if it's so difficult, then how did we beat level one on the first try, no one game boosts used? Perhaps you guys need to rethink your strategy. This game is extremely addicting, as it requires a balance of quantity and quality when building up your defenses. Sure, you might screw up the first couple of times, but that's natural. Just keep trying. Once you figure out the strategy that works best, you'll get on a roll, and assuming you don't waste your SAS dollars on one game boosts and continues (which honestly are counterproductive if anything), you'll get some pretty powerful defenses unlocked. We recommend getting the Ra beam or whatever it's called first, then the Liquid Tungsten cannon, then the titanium anti-tank barricades. Trust us. Those titanium barricades are nearly invincible. Expensive, but they'll hold back even a devastator for several seconds. As for when you're just trying to actually beat a level, we have another piece of advice. Don't underestimate the power of a few upgraded machine guns. The level three ones can handle bloaters, level fours can take on a devastator, and level five ones can hit several targets at once, and will shred the devastators to pieces if they focus all four individual guns on them. They can also take out the boss's health quick enough to defeat him easily. Yes, you will need know how to balance numbers and quality. Just throw in the explosive and special towers here and there for crowd control and extra damage. The Doubleshock is definitely helpful early on, and it stays effective for a decent amount of time. But anyway, the point is that the game is beatable once you learn the mechanics. Rather easily beatable most of the time, we might add. As for those of you saying that getting the defenses that cost SAS dollars freezes your game and crashes it, we have never had a single issue like that. We've had it crash during a round a few times due to a glitch that occurs when too many things are happening at once (it has happened only while we were trying to find a location to place a new defense during a large wave), and we've had the sound glitch out and stop working whenever we locked our device while the game was running (and we quickly figured out how to make it come back without restarting the game anyhow), but never anything like that. So we're not sure, but something tells us it could be your device or internet connection. Or both. Either way, hopefully that gets figured out eventually. So like we said, this game is beatable once you learn the best strategy for your play style. It isn't as hard as you think. We've beaten every level, so we can tell you that from experience. The last one was a pain, even for us, but we still beat it. So it is possible. You just have to keep trying and keep learning. You'll figure out a strategy sooner or later.
We've never really been a fan of tower defense games, until we found this game. This has the deepest and most challenging gameplay of any tower defense game we have ever played. Beating the harder difficulties requires you to think outside the box. Some people criticize this game for being "too hard", but it's difficulty is just a testament to how good the game is. You just have to be tenacious to figure out how to win and you eventually will; on our first attempt, we lost while playing the first map on easy, but we have kept trying and have now beaten all of the maps on easy and two of them on medium.
Great game, extremely hard, but great please add more levels.
Ninja Kiwi has not failed to make a decent SAS game that loyal gamers of the franchise crave about everyday. However, SAS tower Defense like any other SAS game is unforgiving as the slightest margin of error will either get you killed or cost the lives of innocent refugees as you hold back an overwhelming horde of undead with only a handful of Vickers. The game is by all means a challenge even for the most intelligent gamer to handle also like SAS 3 zombie assault their has not been any new updates for nearly a year as the last update was implemented in 2013. What a challenge? Then you picked the right game.
The game is great and hard enough to keep us playing for a long time, a few bugs, but overall it's a great game.
This game is awesome, yet hard love it.
Due to all the nice ratings we'll give the game a try.
Try if you don't like it delete.
We're on wave 150 now and every few waves the game crashes and we have to keep going back into the game. PLEASE FIX.
Ok we've gotta say we've read most of the reviews and the one that got most of our attention is when someone said it was too hard we just got the game a hour ago and the second time we played it we got to round 57 it's really not that hard the timer is great towers are great but still this game is about strategy we've played with Ninja Kiwi since blooms defense 1 we've played the second one 3,4,5 and we've played sas 3 and just a hour ago this and we already beat the first level and great lvl 40 boss.
Great TD only downside for us was at wave 60 the game began to crash with each new wave…ran out of weapons to spend money on LOL.
That game was fun. We finished it in less than 10 min.
But it's one of the harder ones right from the outset. If your an experienced TD player, your going to love the challenge. If your newer to it, go for it, take your time and you'll be in for hours of fun.
As someone who loves zombie games and is addicted to to SAS 3 we can honestly say this is the best zombie game we have ever played.
Great game. Fun and challenging.
Crashes with purchase of perks – need to fix.
So glad we found this. But freezes when we purchase extra damage then we have to restart ipad but it still takes the money…. And you can't listen to music while playing it even while in game sounds are turned off. Was great till this happened. Great td game otherwise! Update: nothing has been changed or updated. App still freezes when spending cash for upgrades.
We like this game. Our first thought is this game very addictive to play.
A little hard without Iap, but still fun enough game. Been a while since we enjoy TD game like this.
Love it. But needs new towers and maps getting tired of the old maps.
And new stuff newer towers or something even more upgrades :) over all this is a really fun app better then any other TD we've played.
Yeh it's pretty good, it's pretty hard but gets easier towards the middle cuz u get tons of money.
We don't know what these other baby's are saying this game is amazing! It's not to hard at all, it's not to easy.
AWESOME! But dont have a count down timer for when the round starts.
This game is fricken awesome<33.
This game is addictive like bloons td 5. Ipad is much easier maneuver items. IPhone version is just as fun. The only issue currently is the in app cash freezes the game for both ipad and iPhone versions. TIP: use grenades.
