UNISG is not everyone's enemy addon

I agree - Duty might fit as well.

Virtually everyone is.

Very true, but unlike the other factions illegally trespassing in the Zone, UNISG is a foreign military organization with clear ranks and command structures and support networks. Them just being there is essentially an undeclared invasion or war.

It's like if it turned out Area 51 was a real thing and China had stationed a group of highly-trained and heavily-armed special forces soldiers to recover all possible information and as many specimens as possible.

Furthermore, Ecologists, while friendly to all stalkers (except bandits, renegades and the different fanatics) still work for the Ukrainian government, and it's unlikely that the government of the Ukraine would be willing to let any outsiders into the Zone, considering how valuable and scientifically important those artifacts are. Furthermore, they have what is essentially a total monopoly on those different artifacts, and were they ever to restart the X-lab tests, they would have insanely powerful psychic weapons in their arsenal.

Now, if it's better for little Ukraine to have those technologies, or if it's better for the global elite and the already-bloated superpowers to complement their world-destroying nuclear arsenals with mind control devices and anti-gravity tech...

An optimist (or perhaps a Freedomer) would say we'd create a wonderful world, with almost-magical technologies and forces harnessed for the good of the common man.

A pessimist (or perhaps a Dutyer) would say that these technologies and forces (anti-gravity, room-temperature superconductors, crystals that break the laws of thermodynamics, etc...) would be used for war and bullying weaker nations first and foremost, and would lead to total authoritarianism.

A realist (I'm biased) would say that all of this, like everything in the world, would only be accessible to the rich or very rich, and the life of the average citizen would not change noticeably, apart maybe from suddenly having an urge to buy more of whatever soft drink company got their hands on the permit to use the mind control device this time.

...sorry for the rant, and I just realized I'm either being too bleak, or not bleak enough.

Still, I think that's reason enough for the Ecos to not be on good terms with ISG, or Duty for that matter - they're already focused on defending the outside world from the horrors of the Zone, and many are former Ukrainian Army personnel, with tacit support from the government.

In fact, they'd likely be the MOST opposed, considering the Ukrainian government can use them as a deniable asset or "proxy group" in order to eliminate UNISG soldiers without ever actually having to go through the public shock of Ukrainians finding out there's a foreign black-ops team operating illegally inside their borders, shooting Ukrainian soldiers and citizens, and the less the actual Army has to fight the UNISG, the better - this is "escalation-to-war"-tier stuff we're talking about.

Besides, if Duty is used as a "tool" against UNISG, then their paramilitary nature makes them even more useful - while UNISG members aren't protected by the Geneva Convention since no war has been declared, only military members are (in a way) bound by and protected by those laws (specifically treatment of prisoners - the government can order Duty to torture as much as possible, and to execute all prisoners, et cetera - there's enough layers of separation between Duty and the official stance of the Ukraine to make it easier to "wash their hands" of the situation.

Sorry if I got too nit-picky, but that's my $0.02. But I don't make rules, and you can just edit the configs yourself, lol.

UNISG are basically the Military but in the zone illegally, they're a secret detachment of NATO and are supposed to avoid contact wherever possible as they technically shouldn't exist. Loners are just regular folk, UNISG would not want them to spread word of their existence/involvement, same for Clear Sky as they are basically unsanctioned Ecologists.

It's like if the government made a "spy" division to infiltrate Freedom, Duty etc. and learn what they know about the zone without informing the Military, they wouldn't be friends because word spreading of their existence would get to said factions and compromise them.

yeah, but MERCS are literally NATO funded due to their equipment

The Mercs are from Private Military Corporations, they aren’t NATO. They’re paid by the highest bidder and don’t follow the laws of the zone, that’s why they don’t have any friends except for the Scientists, because they get hired by them to protect their research.

I think they should be neutral only to mercenaries (and they are by default)
Their appearance in the Zone is meant to be a secret and I think mercenaries have some connections with the US or NATO, maybe they get paid by them (this isn't confirmed but there are many assumptions to this) that's why they are neutral.
In fact, back in 2007 I thought the mercs are some sort of covert US special forces guys, that's why they were after Kruglov and the ecologists, maybe they wanted some data or knowledge about the Zone the ecos had.
