In short: War of Chosen is far better, but this one is better then vanilla XCom 2.

From my perspective this looks like a way of milking players.
"How else we can sell our game engine? Hey, let's do a S.W.A.T. like game, people love how they breach into places so let's add that, and the enemies, maps and most of equipment we have already, so let's just add some lore and here we have it." But on the other hand I paid around 1 dollar for this as the last piece of X-com collection sale, so for that price I had more then my piece of fun out of it.

In general if you are looking for something better and more advanced then Xcom 2 War of Chosen this is not a place, but if you are a hard fun of the series and want some fresh look into series, this will give you what have you paid for.

Also this game plays fine on Linux through forced Proton.

Game was fun when it came out. Tried re downloading and playing it a couple years later. Game always freezes on title screen yet game music will play.

This game doesn't do its predecessors justice.

Everything sucks. The art, the encounter mechanic, the limited squad because of the smaller map size, the story, as well as the font size for every single thing (the text is literally formatted like someone else worked on each word), everything sucks. This series should have ended with XCOM 2 and never should have gotten this terrible spin-off. The creators of this game do not understand why the game was good in the first place.

And it's so ridiculous how this game even exists. I understand that XCOM 2 has to have an aftermath, but what is this abomination of a world. Nearly all humans and aliens in the storyline were heavily affected by the alien invasion but somehow, and I know I might sound stupid, somehow, nobody is racist, xenophobic or anything. They just all don't care and forgot what happened these last few years. How does that make sense? How is it even possible that every alien learned to speak fluent english, when I have immigrant family members that have lived in countries for decades without being able to say "I would like a plate of spaghetti"? Nothing makes sense.

Also incase anyone wants to mention it, I didn't finish the game, because I quit after I went on a mission and literally nothing was there. No enemy, no way to progress, just nothing. Wonderful bug, for a wonderful game and also the most obvious to just give up. This game doesn't deserve a chance. It was already obvious after I saw those ugly 2D drawings that are supposed to represent actual living beings.
