... a Insane Mecha Robot, like the ones from Fallout Universe? Instead of 3 to 4 Raiders, my vault was invaded by one of those. It was so fast, that i couldn't even spare a reaction to that...

Probably a new enemy from the latest patch.

Wait, there are new enemies?

Funny thing was that it has happened before the update, but i was lazy to report it before (write a thread here) lol

Hmmm... How many dwellers you have?

I have never seen this enemy and my main vault gets over run every time I log in. As in, I can log in for ten minutes and usually see at least three death claw attacks in that amount of time, not counting the rad roach infestations, fires, mole rats...

Oh man I would love to watch my Deathclaw-hardened first level defenders responding to this new threat. Haven't seen the robots yet, although I have caught the Mysterious Man a couple times.
