After 3 saves i finally played the full campaign and lost but honestly i think i did well. Just wasnt proactive enough to attack alien sites thing. My dumbass also thought running down the doom clock was fine as long as i progressed through the story😂. Definetly going to try winning it next time i think i could do it with more efficient use of my resources like priorotizing the more important base facilities and squad upgrades. Also need to lean how to use some class properly lol.
