i have never completed the optional task on infected ground. came close last night, but it seems as though every time we get to the last room, right as we went the room the 2 crew members are auto assimilated, meaning we dont have anytime to even try to save them.
is this a bug or has anyone else seen this? or is there a trick to do before the last room to prevent them from becoming assimilated?
Its not bugged as I have completed it a few times now, one of those times being last night. There is a trip point for each room where the guys are, cross it and the workers start doing their thing. And shooting a drone past the line (like that elite in the center of the last room) counts as crossing the line.
In order to complete it you really have to be on a team where at least 3 people know what to do and not have a self proclaimed rambo that just smashes the space bar the moment something they can target is in range.
The best thing to have is 2 eng that know what to do
