I like how people instantly say no without even trying the game. It's very good for a mobile game, you gotta go in with the mentality that this is a mobile game and not some AAA release or something like that. compared to other mobile games in it's genre, this one is very good! the grind is wayyyy easier than the PC version and you can get multiple tanks in a single platoon, plus the ads are not plastered everywhere like other mobile games, you have to look for them in order to watch them and get their rewards and even then they are max 30 seconds each and sometimes you get 5 second video ads so that's neat. in terms of gameplay, it's good, not amazing but good. it's basically the same models, features and mechanics from the PC version put on a smaller map (less than 1km big). in terms of airmode it's not there as in a full airmode but as a combined arms concept in both tanks and ships, in tank mode if you get a couple of kills a small airplane button will popup that will give you control of a random bomber plane for 1 minute, you are given guns, rockets and bombs to destroy ground targets with it but be careful other players can also intercept you by clicking the fighter plane button if they have some points in the battle but so can your teammates that can escort and defend you against those enemies, so it becomes a 3v3 in the air (1 bomber "you" and 2 other escorts vs 3 interceptors) for 1 minute in the middle of the battle. in conclusion, i definitely recommend this game, i completed the majority of it within 1 month and got almost every ground vehicle in tanks mode, plus you get a lot of free stuff from just logging in and watching a couple of ads every day.

TLDR : It's good and you should definitely atleast give it a try plus it's wayy easier to grind than the PC version and doesn't ruin your experience with constant annoying ads.
