The new game plus isn't too special. Tried it and my main squad didn't get ported over which was such a shame... They screwed something up greatly there. But the thing that excited me was the additional optional sliders! That's how you do custom difficulty! You know how a normal Alien attack takes 1 block of health/armor away? You can change that now up to 6 (+5). Yes, one small attack can take out 6 bars! Nice, that's just what I want. Difficulty done not by making the enemies health spongier, but by increasing their damage (speed and or number of Aliens in an Onslaught would be my wish as well but I can live with this...). You can also start the infestation level of the planet to whatever you choose. For us who like to make the game hard but fair/realistic, this is so good!
Still, really wasn't expecting this kind of update about the new features and New game plus (which is a bit underwhelming). I wonder what they have in store for the future updates?
