In the game you either grind, or pay for the purchase of weapons, for equipment, for pumping, for additional units in battle, for pumping up weapons, for hiring new fighters. There is a separate battle pass that you need to buy, or you will not receive half of the rewards that you need to upgrade your equipment. And at the same time, you will still be fucked by a squad of imbecile freaks who were bought for money.
The game is pay2win in its purest form.
A separate joke with the CBT: First, the players paid for the CBT - in order to pay for another CBT inside the OBT. The developers sold premium units for access to the CBT for 3500 - and nerfed them after release.
Now the developers offer to buy a test for one more campaign, for 2500 rubles. For it you will receive two charge-bend units, which will be nerfed immediately after the start of the open phase of the test. Moreover, now these units are head and shoulders above any other units.
The game is designed either for children or for suckers. Both of them, by the way, mostly sit on the off-line. platforms.
Pass by if you want to save your money and your nerves.
