Recently fought "Mechs" enemy type for the first time and it was super challenging but very fun!  I almost died so many times I lost count and it felt very rewarding.

I knew Tyranids and Eldar were added but I had no idea "Mechs" enemy type existed in the game.  Will this enemy type be added to random missions or the regular map outside of void crusade?  So far I have only been able to find them in void crusade but I haven't checked the new 4th galaxy cluster
