Party Hard

This is the sole level-specific trophy, it can only be unlocked in Casino Party (#3). You will notice a room with 3 big stacks of bills and and a few coin bags at the trop right of the building. The robbers mentioned in the description will spawn next to the entrance there shortly after the beginning: 4 of them will attack the bouncer to break into the room while another will act as a lookout further down the alleyway.

To earn this trophy, you will need to kill all 5 of them. Note that if you get noticed by either one, they will all flee and it will be near impossible to dispose of them. To make things easier though, the suitcase located in the room with the bills will frequently spawn a sword. Instead of killing people one by one like your knife, this sword will allow you execute everyone within its range in one blow.

The easiest way to get this trophy is to restart the level until you get a sword from the suitcase, being careful not to get noticed by the bouncer. Let the 4 first robbers attack him and execute them all while they’re fighting. The only thing left is then to kill the remaining robber, making sure he doesn’t escape when he sees you.
