Game abruptly slows to a cripple at 5 level increments, so! As a free game? Don't want to play the same slow level 50 times (I watched 50 ads to pass through it) As a paid game? Lackluster at best.
- Mooserama · v1.0.1
good game
- Led Estonilo · v1.0.1
game is ok what I did not like is i finished level one choses a card the had to watch a video that did not let me leave then had to close the window ro reload the game town it took me back to the start of the game again at leave one ... I uninstall it for that reson
- Lee Bowen
The app requires to connect account, provide permission. I don't prefer that. I prefer to try without providing permissions. Waste of time
- Adarsh Singhal · v1.0.1
A game you can not progress unless you pay absolutely لا تفكر تنزلها حتى
- Mahmoud Alshammari · v1.0.1
Awesome game. I like the idea and I love games like this. In the first place. Yeah, I've been having fun.
- Cayton Nicholas · v1.0.1
awesome
- Sri Wahyuni · v1.0.1
Designed to extract money out of you. the levels are going to get instantly hard 9-10 rounds in so you have to spend money to power up and get past it rinse and repeat 5-10 rounds after again. If you are the type who likes to enjoy standard progression in games, this game is not that. It is meant to exploit the player.
- Ehtisham Ahmad · v1.0.1
nice time killer with no adds yet 😁
- KILLERBOY GAMING · v1.0.1
the ads for extra power ups don't work... just keeps saying ad not ready
- Milan Asis · v1.0.1
The RNG of the cards never works. The game purposely makes it hard to move to the level. Even when you are stronger and more powerful, you won't get the cards for the upgrades you want. I went 8 rounds and only got an upgrade card for my shooter only at the beginning and then no more upgrades for him
- VictorHugo Torres · v1.0.1
cool game
- avery williams · v1.0.1
This game is simple but great! It’s fun to watch your weapon selections play out, work together and do their thing. However, some of the guns could use an intelligence upgrade. The Disruption Drone, Laser and Tesla Coil has a bad habit of literally firing at nothing, or missing out on shots that can do the most damage. (Aiming at one target instead of the group of 20, for example.) Upgrading that would take away the only real point of frustration in the game. (UPDATE): Still waiting for the weapons intelligence upgrade. Some weapons literally shoot at nothing, making the gameplay EXTREMELY frustrating. You spend upgrade decisions to create powerful guns, only to seemingly have them manned by incompetent toddlers. THIS HAS TO BE FIXED! I downgraded my game rating to 3 stars because of weapons incompetence. Also, while all of the item collections may seem bountiful and cool, the stuff to collect are spread out over a dozen pages or more. Anytime I want to play, I end up spending the first 15 minutes going around multiple pages to search for and collect things. If it the collecting could be consolidated so I can just grab stuff and then start playing sooner, that would be more fun and efficient.

was great but they recently nerfed it so I now can't even beat the levels that I already beat 100% and to win anything now you can't skip the ads. 🫠

- Eduardo FA
LIKED, this game. they changed the drop rate in some of the events it takes forever to get some of the purple cards. Which make it more difficult to advance in the event. LAAAAAME!!!!!! DELETE.
- E M · v1.0.1
Played ten seconds. Then a massive ad. This is a scam
- Justin Rigdon · v1.0.1
This game was great until they decided to double (sometimes triple) the amount and length of the ads. its completely egregious and ruins the whole experience. I would even be willing to pay the no ads fee but the pricing is absolutely ridiculous
- Carl Dixon · v1.0.1
its a toxic game where the arrows you choose to continue, bring up a screen that charge you $2.99.... I tried to give this game the benefit of the dought.... Enjoy my money developers... Im out 🫡
- Christopher Garrett · v0.20.1
good game. ads are tolerable.
- Terence Calimpon · v1.0.1
Very fun game if you are wicked patient. RNG in this game is a bit broken, you crush a level, replay and get crushed, in game resources are slow accumulation, and don't get you too far. It is designed to make you want to pull out your wallet, often for mediocre gains. seriously worth a download just to see how many micro transactions there are. It's definitely fun for grinders, or those with significant amounts of disposable income.
- Joseph Digiovanni · v1.0.1
Not at all like the ad.

Fun don't have to pay to win and nearly no ads great easy fun to relax to
- James Young · v1.0.1
After playing it for a few months this was my experience. Fun and easy to level up in the beginning After about a month or so you either got to pay to level up to get stronger or watch 1000 ads. The game is very slow paced to the point its unplayable. They do got an option to speed it up for only $60! lol Try it out and see what I mean. Im deleting it regardless.
- Lu Abed · v1.0.1
a tower defense game where you cant speed it up and you want me to pay 14$ for 30 days? HELLLLL NOOO
- Taylor McCarthy
give us control over our turrets, the dumbfire is incredibly frustrating and stop asking me to purchase stuff.
- Arren · v1.0.1
sucks cant be played during offline
- Russel Jhon Dasigan · v0.13.7
I really want to like this game, because the premise, art style and general gameplay should really click together well, but the grind is unbearable. You very, VERY clearly aren't intended to succeed without buying loot boxes, or watching so many ads that you spend more time doing that than actually playing the game. The greed is unreal, to the point they really don't even try to hide it. I can't in good faith recommend this game.
- John Dark Souls · v1.0.1
you have 12 different build paths, 20 possible upgrades per level, 4 upgrades to level up a build path, and they're random. What is the likelyhood you can get 2 defenders leveled up enough to help? low. so you have to play over and over hoping for the chance. I love the challenge, but its to the point it feels more like a waste of time
- Tym Ford · v1.0.1
I feel like the game recognizes when your doing good so it will purposely give you the absolute worse cards and weapons at first so you cant get what you want to actually be successful. Then when you watch a ad to get different cards it will give you 180 second add and still give you stuff you dont want. You will have to play the same level 20-30 times to finally get somewhat decent cards to beat the level.
- theappABSOLUTELYSUCKS · v1.0.1
you're insane if u think im spending 50$ on the ship card yall gotta bring that down
- Jordan Scott · v1.0.1
im starting to hate the long ads they require you to watch, a 10-15 seconds is bearable but more than that, it makes me want to uninstall this game
- Arman Catalan · v1.0.1
👍
- Gunawan Tjoa · v1.0.1
Can't play the game unless I give it access to my name and email. That's an instant close, uninstall, 1-star rating.
- Adam Bowler · v1.0.1
fun, addictive gameplay. NO UNREWARDED ADS!!!
- Blair Frost · v1.0.1
Fun game. Requires a bit of money if you want to progress fast but lots of good events to get what you need for free. You will get stuck on stages, some are passed with luck others are passed after 100 attempts.
- Peter Ashton · v1.0.1
Great fun to start with! I'm sure it will soon become nearly unplayable without paying in vast sums of cash.
- Jon Clabo · v1.0.1
It's a good game but it has a prioritization on trying to make you use all weapons, which most of the weapons in this is stupid and not worth your time.
- Christian Flores · v1.0.1
Really enjoying the game — it’s fun, polished, and easy to keep coming back to. But the in-app purchases are ridiculously expensive. Just for a fast forward button - ₹990 for 30 days and ₹4,950 for lifetime benefits just doesn’t feel reasonable for a mobile game. I’d happily spend if the pricing was more sensible and offered better value.
- Anindya Sengupta · v1.0.1
not bad not really what's advertised
- Crisqyx · v1.0.1
Beyond the usual with these types of games (using RNG and circumstance instead of skill) the game has what seems like purposeful glitches/crashes. Whenever i get a good setup going the game crashes at random times in the level. ONLY when i have 4 great towers. Its like it nows i have a high probability of beating the level and decides it wants me to stay longer so it crashes and looses my progress. Now it may be the turret combinations (beam, elec coil, flame wheel, aeroblast) but idk it seems to be any winning combination. Its so consistent i could get a video of it within 5 mins. Disgusting practice if this really is the case, wont be spending any more time on this game until an update addresses this

Kinda hard but not opressively ad ridden.
- Lykomedes · v1.0.1
Stage 1-4 full completed. I'm level 12.5. I can barely make a dent into the boss of stage 5... Seems like it asking to be paid to win or something.... Hhmmm
- Not not Sure · v1.0.1
Good game.
- John Cantillas · v1.0.1
I’ve been playing for 6 months and logged in one day to find everything wiped
- Jq commando · v1.0.1
fun game but sadly ruined and it gets frustratingly repetitive after about day 2. like you have no control over the type of powerups you get and most of the time it gives you powerups for old weapons which pretty much leads to you playing over and over again until you get the right power ups . it shouldn't be this way and you should be able to equip 4 weapons and based on that you get powerups and that would be the better approach . never been fatigued of a game that I actually enjoy so quickly
- Kirath Gaming · v1.0.1
…. U play until u get to level 5 and that it u want to pass that unless u buy somthing . But the game ant worth a dame so there’s no point …. I played level five 13 times. It should t take that much I don’t take app games serious anyway but this is stupid . Delete before u give yourself a headache … or never downloaded it to begin with with
- KenDraiL YOO · v1.0.1
$10/month or $50 lifetime to play the game at 2x speed (yes, anything cheaper locks you to 1x in a game that's mostly idle waiting until you get to choose upgrades or watch an ad for more upgrades), ad skip is also restricted to this same tier. Maybe the game is enjoyable if you spend $50 on it first, I will not be doing so and also will not be wasting any more time waiting idle at a snail's pace for gameplay.
- EllaVil · v1.0.1
Was a Super fun game. 5*. But events cheat. Vanguard is super rigged. No one I know in the groups likes it because all they face is bots and paid players, with the devs doing that to try to get you to pay. I can confirm now that Vanguard actually cheats. I watched as the opponent only got 10-20 monster every wave and I got 50. 100% cheating the player. Report the game and devs for being a scam. Needs different events that do not cheat you. Remove Vanguard.
- Pitsch91187 · v1.0.1
This game is like crack if crack stopped giving u anything in return. There’s fun and I’m still playing but the p2w is the most egregious I’ve ever seen. Like 50 bucks for something that’ll get u a few stages. Get serious
- Aeon123go · v1.0.1
Was fun to start but progression is glacial and they just slapped a whole new type of game in. Kind of sad I spent money on it.

Support not great. Been playing a long time. Due to developer mistake I am now forced to re-buy loadouts I've already previously purchased (in game it's says you can reinstitute purchased ones for free but that's a lie) Frustrated after spending real money on this game.
- ticklerlickler · v1.0.0
This game is pay to win at its finest even the updates are another chance to suck your money dry. To be anywhere near the top of the weekly leaderboard events you must spend about 50 dollars a week. If that’s your cup of tea then this game is for you. A lot of time is spent grinding if you don’t pay up. It is definitely a long road ahead if you don’t spend money. This game gets boring after you realize it strictly pay to win and not skill based.

3 min of ads just to get a different card is crazy and is so bad like its gonna make ppl delete it

Pay to win as hell and the grind is crazy but it’s fun 👍
- Gk_Gaming65 · v0.20.0
Can’t accept anything ad related rewards, turrets, etc. other than that fun game to kill some time with
- Nandeskaa · v0.20.0
It is a fun game early on, then as you gain skill level it becomes what you think is random but it is designed to convince you to buy your upgrades. So play it for a few weeks, when it starts to slow done your upgrades just know that you are being manipulated and move on to the next game. It has potential but the ruin it with pay to play, but most of the do and that is the model for the foreseeable future, just like at these games as a buffet, try them and the leave to the next one.
- Sick of ads that lie · v0.20.0
It takes forever to advance in this game, & it’s basically pay to play.. smh. The rewards are very low & trash.. 2 out of 10.
- Blackness88 · v0.20.0
Well, I finally did it. I hit the point in the game where you stop getting meaningful progression without spending into $500 event packages. I event bought the VIP ad-skip pass and the occasional monthly pass but those don’t get you to the next tier from where I am. Fun while it lasted. The next tier is for the whales.
- Koji Suja · v0.20.0
I’ve been enjoying this game very much for the last few months. There are a few minor things that would be awesome if they are possible. 1) Slightly smarter targeting for the main gunner when targeting invulnerable enemies/ enemies through which bullets cannot penetrate. It would be nice if the gun would target enemies it could actually damage instead 2) If it were possible to have a toggle for the gunner to continue targeting the nearest enemy while you are actively moving them around on the bottom, that would come in handy as well 3) Having some way to play with/ interact with your friends (and having a friends list) would be sweet. Either playing a stage with them or being able to trade gear or something Thank you so much for your time and energy!
- ModeratelyOkay · v0.20.0
I’ve been playing this game for a while now and don’t get me wrong, it’s fun! But Jesus is it a grind. You get to the point where it takes so many days of grinding rewards and upgrades just to go up 1 stage. And the rng is absolutely terrible. You spend so much in game currency for chances to gain helpful bonuses, gear, and items and it almost never falls in the favor of the player. I’ve been playing this for well over a year and still only have one fortress frame….dont play unless you like this ridiculous grind…
- Dude Fat Head · v0.20.0
idiotic system of dropping cards, I physically can not pass the 5th stage because I fall a lot of unnecessary garbage instead of upgrades, as a result, the game is deleted
- boy11164 · v0.20.0
The game play is fun ..but is soaked with long ads that make it cumbersome to play .
- Johnclintonlopez · v0.20.0
I’ve played this game well over a year now? The current event really has me annoyed, I am a pattern recognition person. The patterns on the energy extraction are undeniably incorrect. There was a solid 3 times where it would go one extra ding and slot so I wouldn’t get the 1,2,3,or 4% of the gyms. Very agitating to say the least. Games okay but it seems like it pay to play in my opinion,
- SumCoolFr · v0.20.0
The gameplay footage in the add does not accurately reflect the real gameplay.
- Tothenext1 · v0.20.0
The most important feature for the developer on these free games are the ads… but the sound will disappear every time you watch an ads, you have to restart the game for the sound effect to work again… very annoying… destroy all the fun
- ybing · v0.20.0
Your ads are almost 3min long. Totally ridiculous!!! If I could give you no stars, I definitely would.
- Trevor0123 · v0.20.0
wish there was a option to get extra cards like watch a add or something. otherwise love the game.
- Matt Bell · v0.20.0
The latest event is horrible. The RNG is extremely unforgiving. Purchased premium tokens. Glad i spent small. RNG is very unforgiving in latest event.

- LvL_RimmyLeBeau Y Gambit · v0.20.0
Frustrating cash grab I've played through this game twice under different accounts, at around Level 40/35 you just grind against undefeatable levels. Navigation is confusing, it wastes your time digging through screens to get rewards. Adverts are LONG! Upgrades are ruinously expensive. Guilds are poorly run and difficult to join. It's a nice concept, but unless you have VERY deep pockets or about five years of spare time, I'd give it a miss.
- Chris Skelton
ads of the game said no ads. then there are ads. you don't have to watch them sure but they are still there. I'll be removing them and keep playing because the game is fun. I'm not going to pay for it though.
- wolfONdrugs · v0.20.0
it good
- ringofart · v0.20.0
game is absolutely infested with ads. most give close to no benefit for a 2min ad. to illustrate: daily ads: normal key, gold key, coins, guild donation, double rewards, stamina, mecha egg speedup, auto patrol, card refresh, event ads. there's 2 projects per week where you watch more ads than play the game! give this a huge pass
- Makchu Cook · v0.20.0

Monthly subscription to remove ads, and just throws purchases in your face every chance it gets.
- Dakota Turner
game is fun definitely a pay to play kind of game after a certain point. The events will not let you hit the big rewards unless you pay. ive been playing for about a year and a half and never hit a big bonus on any event. the events will get close but change to make you miss what your trying to get or it'll make the enemy stronger so you lose in some events.
- patrick williams · v0.20.0
Subscriptions are very expensive
- omar gamal · v0.20.0
the heaviest P2W (pay to win) game. you won't progress unless you pay. waste of time and space. 1 star game
- James · v0.20.0
Half the time the ads navigate you to another window and close the game losing all progress. Takes 5 minutes just to log in and click everything U need to do before U start an actual game.
- Kayl Jeffery · v0.20.0
Good.

This was the game i was looking for to play forever! U dont need to donate to play it its so good that time just flies when u play it! Recomended!
- Luka Ralevic · v0.20.0
nicely developed, but the random selection of buffs ruins it. the variation of stages and mob waves should mean I select from the full range, even watching the ads doesn't help. I stopped playing it now.
- Mark Montague · v0.20.0
drop rate of good cards is too low
- Abhishek Khorwal · v0.20.0
The game is fun at first, I give them that. It has a lot of potential even with all the wacky "praying to get a lucky card streak". However, my major letdown is the greeeeed they have for money. Yes, there is option to watch ads for extra content, however why everything is locked behind ads and all of them are so long. Like a minute or more each ad. You just waste 30min a day if you unlock all the content behind every ad. About the money, insane pricing. They're literally shooting for the stars.
- Nikolay Atanasov · v0.20.0
I love sky guard and I love this game and it's smooth

- Lala Lari · v0.20.0
got hooked on this game for a few months but without pay to play add ons and ad skips it is unpayable. and the price for those features are enormous for a mobile game. 1 star great time waster game turned into a complete money grab. very disappointing.
