OK, yesterday i was in playing iron serpent trying to get a better score and all was going well. Today i go back in to try again and over and over im getting owned hard. every enemy with very few exceptions nails my guys over and over from seemingly any range as if their aim has been buffed. The Giant robot at the far end that before never woke till i finished the first grp and engaged it now wakes on turn one and comes to join in. only change if made in tactics is to engage the boss first before he crosses through the train to the far side. Has something been changed to increase dificulty and give the enemies an even greater handicap?
