Hilariously Glitchy. Also really really really hard to be competitive unless you spend a lot of money. Also, the algorithm places you in a battle based on rank and not tank type. So if you grind it out, you will be outgunned every time. More than likely you will get frustrated and delete the app as everyone tries to get the lowest scores possible so you will get crushed in your WW2 tank vs an Abrams. There are very few competitive battles so you will find you drop out of a lot of matchups.
