Still got ads. The ads are at a painful level in this game. They also interrupt gameplay, which has to be the dumbest choice I’ve seen in a mobile game. Level 5 is where the game truly starts to break down. The more towers you unlock, the more painful it is to keep up on upgrades. The more towers you unlock, the more painful that random 3-tower choice becomes, especially after you level a few times during the gameplay. World 5 indicates the money tower is important, but I don’t see how. It’s a terrible attack tower and it does not generate enough extra coins to counteract the boss’ star-eating ability. Unless you got lucky on some random chest you will only have the base level money tower when you get to this world. World 5 wins and I quit. ### 3/5 — Still haven’t fixed any problems and don’t care to *2023-06-07* Good game but the stupidity level the devs greed makes it unenjoyable. I put this game down for a year because it was almost impossible to play unless you paid a lot of money right off the bat and the amount of ads that you have to watch regularly just to continue playing is still absolutely stupid. I won’t pay money until the developers prove to me that they’re not just trying to grab money but actually provide a quality product… this is not it. Goodbye once again and probably for the last time. ### 4/5 — Great game, weird mechanics *2022-10-18, version 1.3.2* So far I’ve gotten to world 7 and the game has been great! Except that some of the pomps have WAY to much health like the purple ones that usually come from the balloons. I’m not sure if they require a certain element to kill so maybe you guys can add a category where you can review monsters you’ve fought and their weaknesses. Great game tho ### 3/5 — Great Game… Ads are worse than most *2022-10-04, version 1.3.2* Ive played many a great game with ads and paid to remove them at most. I paid to remove ads on this one. Only to be hit with 1 min + adds for rewards(after download this game screen time). While I understand making money to support updates and the developers, making the game more advance-able to players that don’t want to pay for everything=more players. Great game, but ads after paying to remove the super annoying ones still take the fun away. ### 1/5 — This game is for you if… *2022-09-12, version 1.3.2* If you love ads… I don’t mean just ‘like’ them, I mean really really LOVE them…. Like you want to watch an ad for 60 seconds and then 15 seconds later you are just itching to watch another, then this is the game for you! Decline an ad for a reward only to be immediately forced to watch one for no rewards? YES! Desire more ad time than game time? They’ve got you boo! No 15 second ads here either, oh no.. this game has all the 60-90 minute ads you’ve been looking for. Look no further! Auto-ad… er I mean defense is the best ad streaming app on the market! ### 1/5 — Change name to AD Defense! *2022-08-16, version 1.3.2* I’ve never seen so many forced ads in a FTP game in my life. Post level bonuses or ways to get in-game revenue without spending real money are fine, but this game literally interrupts you 4-5 times throughout the first non-tutorial level!!!! And that’s not including the 3 ad opportunities that I turned down - It made the game utterly unplayable which is a shame because I was enjoying the concept if it weren’t for the company greed. Guess I’ll be deleting it and know now to stay away from “unity games” in the future…. ### 3/5 — Great game *2022-07-27, version 1.3.2* This game is super fun good graphics, good game play. There are some glitches with grabbing your tower to place it and it disappears. In the duo play really fun, could be great fun if it really was a real player, it feels like your playing with an auto bot. Reason for saying that is because the other player in duo never merges towers above 1 or 2 stars and always gets rid of purple and gold towers. Fun game but would be great if you played with real players and in a alliance or something. If it had these two factors I would give it a 5 star rating. ### 3/5 — Great till world 8 *2022-06-22, version 1.3.2* I’ve been playing the game for a min now and everything was going good till I got to world 8. Ever since then if the game starts glitching out. It freezes randomly and at times when I’m really close to beating the world. I still keep playing hoping that it won’t freeze on me and have to start over. If you coils take a look at it and help figure out why it’s doing this; that’s be great. ### 2/5 — Very fun but suffers from painful ad experience *2022-06-15, version 1.3.2* This game is really fun in my limited experience. I was able to complete several levels and things started to click. The towers are interesting and diverse and the flow seems pretty entertaining as a whole. The problem is the ads.I had to watch three before I was able to complete two levels. Plus the option to watch ads to increase certain stats. Which is understandable as they need money to develop, but it becomes too distracting to be able to enjoy the game. I’d happily pay several dollars for this outright in order to appreciate the hard work put into developing this game however I can’t stomach it while having to waste 25% of the game time on watching advertisements. I really wish publishers would move away from this free to play economy it does no favors for the game and the hard work put into them. ### 5/5 — Pretty Good. Can’t lie. *2022-05-27, version 1.3.2* This game’s amazing! I have some suggestions to make it better though (not that it really needs it) Artillery: A tower that looks like a railroad gun (WW2 Era long range artillery weapon. It usually was put on a large support area on a railroad, hence the name) It has very long range with its explosive shells and is absolutely punishing when it connects. However, it is quite slow at firing. The synergy could be either exploding shots or longer range. Pressure Blaster (The devs can come up with a design for this one): It squirts out highly pressurized water that is absolutely devastating to be hit with. It’s short range (Does more damage the closer you are to the tower), does plenty of damage, and slows down and knocks enemies back. The closer you are to the tower, the more knockback you receive, and same for the slowing. The synergies could be either knockback shot or slowing shot. Thanks for this incredible game, and keep doin what you do Gameloft! From, KingGhidorahKaiju ## Frequently asked questions about Auto Defense ### What is Auto Defense?
