The ungrateful bastards !
The X-Piratez Gals just put their boss to the plank after a mutiny.
Despite a very lot of successfull missions and only a few fails, the score went to the negative way too much for 2 months leading the various factions to retire their founding, leading the Gals to think they would be better with another boss.
At first i was really wondering why i was getting such horrible score despite i was making lot of points in missions, then i remembered that under the hood of X-Piratez there's still old UFO: EnemyUnknow/X-COM: UFO Defense.
Meaning that there are enemy/alien missions that i didn't noticed that landed and succeeded in their own missions out of my radars (i had 2 bases one in north american and one in europe but definitively should have made more base only for the additional radar coverage).
Some of those enemy missions can lead into losses of point each days that can result into really massive loss of points after some time (and to keep me so negative score, considering i was still winning lots of missions there must have been several of those hidden alien missions going without me knowing).
The reason of that loss is very likely due to me not reading spoilers about how to reach specific technology (never managed to obtain the hyperwave decoded by example) , because X-Piratez as insane amount of more researches than old xcom to do (and some being absolutely not obvious, opening a tech research because you researched something else that was apparently unrelated) there are lot of techs i have been unable to obtain that would have prevented this bad ending.
And in x-piratez you have a very low tech to start with, and progression of tech is slow, much slower than old xcom, so it takes a lot of time to reach a point you can counter those alien hidden missions.
So before playing X-Piratez make sure to check how to obtain some must-have tech (and how to get tech that allow you to actually shoot down shipping instead of tailing them hoping they land before you get out of fuel) , so you can avoid this kind of unfun.
