A very nice game, but in the beginning only because you can compete, but when you reach level 18, it will become impossible if you do not pay money for the game. There are also very expensive and stupid weapons, such as lasers, very stupid weapons and expensive planes. The game has become very boring.There is no balance in the levels, corresponding to very high levels, and they have very powerful weapons and planes, as soon as you enter you will be eliminated.
