Update 2: February 5th, 2019: A post on TwitLonger from the official @MetroVideoGame handle has looked to bring a more positive outlook to this whole scenario, in an attempt to bridge the gap between a lone developer's sentiment and the entire 4A Games studio. The post follows:

The recent decision to move Metro Exodus from Steam to the Epic Game Store was made by Koch Media / Deep Silver alone.

The recent comments made by a member of the 4A Games development team do not reflect Deep Silver's or 4A Games' view on the future of the franchise. They do reflect the hurt and disappointment of a passionate individual who has seen what was previously nothing but positive goodwill towards his work turn to controversy due to a business decision he had no control over. We respectfully ask that any and all valid feedback over this decision is directed at Koch Media / Deep Silver, and not the developers at 4A Games.

The future release strategy of the Metro series lies with Koch Media / Deep Silver. Our decision to partner with Epic Games was based on the goal of investing in the future of the series and our development partner at 4A Games. We have every intention of continuing this franchise, and a PC version will always be at the heart of our plans.

The entire handling of this issue has seen wrong turns of hand on all parts involved, the way this particular editor sees it (my, Ravenlord's, sole opinion and not TPU's, so as to avoid a Metro-style situation here), whether it be Valve, 4A Games, the lone developer who made the initial comments, and yes, the particular users in the Metro community that reacted too passionately, inflamming what was already a sticky situation. I, for one, will never see the justice in extrapolating one "wrong" move as a reason for bringing down either the trust or confidence in a whole team of people working hard to bring their creative vision to life. But I suppose gaming is like a relationship, in a way. You can read the original story below.

The whole Metro Exodus saga has been getting uglier as we get closer to launch date. We had reported earlier this very week how Metro Exodus had jumped over to the Epic Games Store for a timed exclusive through February 2020, with Valve and THQ Nordic putting out statements on this move. The move was clearly an unpopular one, and arguably for valid reasons too, but this then led to the mob turning against Metro 2033 and Metro: Last Light by leaving an extreme number of negative reviews on the respective Steam store pages.We do not agree with this behavior, but neither do we condone what happened next. A user by the handle scynet on the Russian Gameinator forums claimed to be one of the developers on the Metro game franchise, and expressed disappointment, and even anger at the review bombing ongoing. Perhaps emotions took over, when he then effectively threatened that the Metro series would not come to the PC platform again, and be a console exclusive, should this behavior continue and also if PC gamers in turn decide to not buy Metro Exodus as a result of the move from Steam to the Epic Games Store. We will note here that (a) the identity of said person has not been confirmed to be an actual developer for the game, and (b) such decisions are usually in the publisher hands. Regardless, both parties are not showing their best here, and hopefully cooler heads will prevail soon.

[Update: Feb 3, 2019: TechPowerUp user birdie has provided what appears to be the most accurate translation at this time, which can be seen past the break.]

An English translation by a native Russian (TechPowerUp user birdie) is seen below.

I've watched the shit storm that gave me contradicting impressions. On the one hand, Steam withdrawal was dubious, no one before us has done this so abruptly (as far as I know). This is new and and it could have caused resentment. And also this move makes it necessary to install the Epic launcher, so it could have inconvenienced certain gamers, and caused resentment.

On the other hand a reaction of the certain category of players ("torrents" only and likewise [he meant those who pirate games]) is hardly adequate. I've got the impression that people didn't really want to play and they have been waiting for a reason to pour out bile. It turns out that we (the developers) have toiled over for years trying to create something extraordinary but a certain category of players believes that our work isn't worth two minutes of installing a new game launcher. Naturally, it's their life and right, but why do they care about Metro at all? Obviously, they are not interested. I can only say that they've never been our players, they are not interested in our work, and as a result, for example, I'm not interested in their opinion. What's the point of me (and not only me) listening to their opinion?

But! Let's take a deeper look at the situation. Someone says that having shit on Metro Exodus and other games of the series has made the world a better place and put the greedy developers in their place. For that, I can only say that, at the worst scenario if all [PC] players boycott the game, then future games, if they get released at all, certainly won't be for PC. Will it be for the better or worse, is up to you. Personally, I will be sorry for devoted fans. But it won't change my appreciation of the work done by me, my friends and co-workers. I'm absolutely certain that almost everyone who is smearing us on the internet is not capable of the tiniest part of the work already done, and I hope, is yet to be done. Which means they are totally unaware of what they are talking about.

One extra thing. Despite the fact that during development I've finished every level of the game countless times, I still love playing Metro. I've completely finished previous games of the series several times and right now when we are putting the finishing touches to the game I'm going to finish it once more. For me it's already a tradition when I finish the game right before its release. It allows to evaluate the work we've done. What am I talking about? I remember the words of Prof [some nickname presumably - no idea who this person is] which I've heard straight from him several times and also on the Internet: you must create a game for yourself, so that first and most you like it yourself. And only now I'm starting to fully understand that - no smartass will make me doubt the work we've done. And there always will be the dissatisfied.

This does not seem as feverous as initial translations make it out to be, however the underlying tones are still applicable to the same bottom line. We also are more confident now that the original poster is a verified employee of 4A Games, and likely a developer on Metro Exodus as well. He/she is no doubt passionate about the work put in to the game, and ideally recognizes that the deeds (however undeserving the review bombing of past games may be) of some members of the PC gaming community does not speak for everyone. At the same time, this does not mean that 4A Games/Koch Media/THQ Nordic/Epic Games Store are all blameless in this debacle either, just that here too the work of few is affecting the rest adversely.
