Oh damn.
I never researched the eurosyndicate before and if i had knew i would not have.
Eurosyndicate unlock some -truly good- but -extremely- expensive laser weapons. But it also unlock eurosyndicate missions.
Eurosyndicate mission are "kill everyone" missions that are filled with more than 30 hostile government folks (some very strong in power armor) and of course killing them = negative score because they're governement, and because frack the player all of those guys see through smoke screens (i tried) and through the night at even larger distance than a Gal in Night Ops armor ! so what the hell.
And to make it more anti-player it seems that every items you put into your ship isn't put in the spawning building, so once you're out of mortar shell carried by your Mortar expert, you're out of ammo :/
And you can't even flee because there's no ship, you're spawning inside a building (and trying to flee there still do not count as being in the ship), so attempting to flee will have you lose all the gals -and- the ship you came with :
You maybe think so just "don't do the mission", except that you're getting a massive score hit if you don't +/- -1500 points, the missions only stay available for 24hours (before you get the big negative score) so if you're waiting for those super slow black market shipping to finally give you the weapons you want before such silly assault like i was doing, it's stupid hard
But those laser weapons are so nice argh purchased 6 eurosyndicate marsklasers and a hundred of ammo clip for more than 3 millions
