Guide
1) start Loyalists mission, upgrade Bend Time II, and you should have some sleep darts.
2) open the door, stop time, then sleep dart 2 chatting guards and 1 guard trying to enter the door to pub. better do it before that guard opened the door.
3) blink to front of the door to pub, open the door, stop time, then sleep dart 2 guards by the bar. there should be some more guards around, you can sleep dart them too.
4) drop bodies just outside the door you went in. let the tallboy see you, then go inside. that tallboy will kill all bodies outside the door. the first 2 guards don’t even need to be moved.
