so whatever happened to those awesome Mech's you had in EW? Isn't the expansion cannon? Would be cool to have them in XCom 2 :/
The M.E.Cs are being used by Advent. I think that Jake stated, that since XCOM lost. EW never happened in Xcom 2's timeline. That being said, Advent uses M.E.Cs (not sure if that is a spoiler or not) although they are fully mechanized.
