Not “pay to win” but gives false hope without

Let me first say that this an awesome game! Would be 5 stars, BUT…The tower strategy really adds to the game and I appreciate how hard it is. However that being said, the game is not “pay to win” and very challenging, but it’s very odiously “exploit the players love for a great game in the first week”by making the weekly boot camp event impossible to obtain without paying. Weekly events in games should be hard, and it’s okay to incentivize players to pay for a leg up, but this games boot camp that promises the starting livery tower as an award basically locks the desirable rewards behind daily goal tokens that can not be obtained by casual play. I strongly doubt it is even possible to reach level 20 and elite level 15 in a week with in game purchases . I have been playing too much in the past week and have only been able to obtain 60% of the points needed to complete the event. In addition to that, the costs for the micro-transactions are exorbitant, to say the least. $50 dollars for the VIP ad removal permanently is insane when a console game charges $60-80 dollars. All that said the game is not, I would say pay to win, but it’s certainly “pay to fully enjoy without false hopes”. You have great game, don’t take advantage of that to exploit players.

One simple change..

One simple rule change would help a lot. That is, no single draw of card offerings should be 100% new towers. There should always be at least one upgrade card in every draw set. Too often in early round, you get a set of cards that are all new towers, but the towers being offered are effectively useless until upgraded to at least level 2 or 3 with card upgrades. At that point you already know there is no way you will keep ahead of the enemies long enough to get some useful defenses set up and instead you just quit the round and start over. Beyond that, I will say this game is fun and keeps me coming back, generally. But it is grindy to the EXTREME. You fight your way through 4 levels in an hour and then hit one of the boss levels and it will be 2 weeks irl until you can level up enough to get past it. Then repeat. I know this is done intentionally to drive people to pay-to-win options, so I’m not holding my breath for it to change. But the balance could be slightly better. It’s so extreme. Also the towers could be better balanced. There are only a handful of towers that are actually worth anything and the rest I avoid like the plague. My ideal load-out: beam, hive, tesla, and disruption field. And then pray I get the good upgrades early enough in the round to have a fighting chance.

The game is hard for a beginner to pick up and start playing just in lvl 1 I only had about 5% of my hp left and it didn’t really help that every thing I did upgrade didn’t help since the moment I got it I would get swarmed by 100 more things to destroy so it made it hard to play with out almost being killed and the 2x speed says it’s unlocks at lvl 2 but no it’s just a way so you buy it even if you get all the best upgrades it makes it insanely hard to survive sure some people like games like that but for a mobile game it doesn’t really work if all your doing is standing still not even having needing to do anything at most you put this on your phone while you do something like playing a different game on pc or console just look over at it once a hour just to see that your dead in about 1 minute from then and even then I just looked and it says the age rating is 4+ who do you expect 4 year olds to even get pass lvl 1 your probably thinking the kid will spend money off of their mom’s card so you get free money even the starter pack from another review says they got stuck back at lvl 5 after buying it and it would take way to long to grind for to get pass the next lvl so good job you made one of the least fun free to play games known to man kind

"Super Mode" might as well be mythical. Difficulty ramps up way too much

I've been stuck on the same level for at least a month, playing every day anyway for some reason. I've leveled up my guy and my equipment, added equipment, added rangers, tweaked my load outs again and again. This is pointless. I can barely make it halfway through the level I'm stuck on, and that's only if I get very lucky with my turret pulls. About to give up and uninstall. It's not fun to play the same level over and over and just get stomped. Update: because I'm an idiot/masochist/obsessive, I'm still playing this game. This problem is still a thing; it wasn't just one level. Once you get to a certain point, the difficulty increase between levels is exponential. Also, as neat as the various turret functions are, you almost certainly cannot use them to their full potential. For example, there's something called super mode for each turret. I've had that theoretically available for all my turrets for several months. I've only ever seen it a handful of times, and only for my main guy and one other turret. Honestly if that doesn't change somehow, and soon, that will be the reason I uninstall.
