I played this pathetic excuse of a game on easy, the developers probably need to google the word "easy".
Sometimes i had to reload the same save for 15 (!!!) times, and even then i gave up in the end, cause the game is too hard. RIDICULOUSLY HARD.
I have no clue why it gets such high scores, it's infuriating.
And that idiotic judgement clock, which takes all the fun out of it.
If you want to enjoy XCOM, play the first game.
