Some of the stuff they talked about before release. Wait for someone to shoot a gun freeze time possess them and walk them infront of the bullet leave the body and wait for time to start again.
The grenade thing is wait for them to throw a grenade then freeze time grab it and throw it back at them if I remember right.
I loaded Boyles manor and Im shooting like 6 people in close vicinity in the head with stop time, and the achievement doesent unlock :S They are really close no way theres more than 1 second between them.
Hornets nest is definitely bugged atm. I waited for NPCs to line up perfectly and shot 6 people in the head at the same time (each bolt an inch from their head) when stop time finnished they all die synchronized (all head shots) and no achievement.
I did Hornets Nest by freezing time and placing an upgraded Springrazor in a group of 6 weepers (the group in the first floor of the house that can be used as an alternate route to the Boyle party)
I caused a true unintentional suicide (and on a Clean Hands run!). I froze time and knocked out a guard and a maid. I picked up the guard to hide him, and when I came back there was another guard lying on the floor, dead, a pool of blood around his head.
For Hornet's Nest load up Lady Boyle's Last Party.
- Cross the street to the mansion, avoid the Tall Boy if you can and make your way to the lone guard on the right side of the mansion. - Sneak past him and enter the alley. At this point the game should auto save. - Prepare stop time and your crossbow - Activate Bend Time, move in front of the stairs and turn left to face a group of Weepers then spam away with your crossbow until time stops.
Repeat it if you don't get the achievement/trophy.
