I obviously don't understand Russian, but judging from the title of the topic alone, I would assume you're asking for a 3rd person mod...
And I don't really see it happening in KF2's current state to be fair. It ain't as simple as it might sound. Usually, shooters are built specifically with third or first person in mind. Plus, the only situation I could see it being useful or even fun to use would be with the Zerk... And even then: precise strikes to the head are usually required to perform well. Which I couldn't really see in a TPS setting.
Without a crosshair, and with such a strong emphasis on accuracy, playing the game in a TPS setting would just feel wrong in my opinion.
