Bottlecap mined Dunwich using CSA then switched to other armor and got myself 'notcied'
Didn't trigger all the mines but was funny to walk about hearing the booms going off here and there. CSA and bottlecap mines = fun time :hubbahubba:
Perhaps learn Mr Crowley's route after he has the keys and place mines beside the cars he wanders past, in some places there are a few clustered together that can create a nice chain reaction, better at night of course.
At the end of my 2nd playthrough of Zeta I bottlecapped the places that incoming aliens spawn onto the command deck, that was fine and also had the bonus of taking out Paulson and the Samuri (at the time I was devastated I killed them, but when I saw what kit they were carrying I was well chuffed!)
