Hello, Soviet Army! Thanks for your review. It's a pity you cannot recommend the game.
Following players' suggestions the shop system was overhauled. You can get Kredit box guns for the in-game currency. The rest of the items you can buy are mostly cosmetics and don't influence the game balance. Moreover, there are regular events that yield decent guns and increased rates that help to level up faster. So you don't have to invest anything to play comfortably.
The game developer you mentioned has nothing to do with Warface.
I hope you'll give Warface another try and change your mind.
Keep in touch.
