After all the XCom talk over the weekend, I decided to buy the Enemy Unknown and Enemy Within games with two other pieces of DLC. This game looks pretty awesome. Hoping that it bridges the gap between now and Fallout 4. I'm not far past the end of the tutorials in Enemy Unknown but this game seems to ramp up the toughness pretty quickly. Kinda stuck on a mission and uncertain if I have the wrong team or have the wrong strategy.
You'll figure it out.
Generally you want to have one of each class (Sniper, Assault, Support, Heavy) and by the time your squad size expands to 6 you will have a feel for which two you want to double up on.
Personally I think my must have guy on all missions is a sniper with Squadsight. I cannot tell you how many times that guy has saved my bacon. On the toughest mission in Enemy Within my go to guy "Vampire" a Sniper Colonel (
Squadsight, Damn Good Ground, Disabling Shot, Opportunist,
In The Zone) went on a nine shot kill streak that without question saved my entire team from destruction and probably saved my entire game overall (the bolded abilities above are what allowed that to happen). It was a thing of beauty.
