Opinion about PUBG ivent
From ex-PUBG player perspective: well, this is the stable PUBG curve, which has been overlaid with basic PVE content. It's fan-friendly, but there's not much content in it, and if you keep playing it, it's just for the sake of the battle pass.
From PD player perspective: this is literally "we have PAYDAY at home". There is practically no randomization, many things from the trilogy are missing (hostages, for example), plus PUBG problems with its curvature are superimposed (I wouldn't be surprised if the event was done for a long time because of the bad code of PUBG itself). Yes, it's fun to play, but I don't see a reason to sit in this mode if you can go to any part of the PAYDAY series and get a much better experience.
So yeah, this is a very strange mode that PUBG players will like, but for PAYDAY players there is nothing to catch there.
