Trophy Description:Killed 5 enemies while you are drunk.
Silver Trophy.

In order to be drunk, you will need to drink 3 bottles of alcohol, whether it is beer or wine or a combination of both. You will know when youre drunk as your screen will go blurry and distorted. The most obvious place to find alcohol is in bars. There are three in the story that provide opportunities to get these kills: Founders Lodge in Raffle Square, The Graveyard Shift in Shantytown and the Salty Oyster Bar in Emporium. Round up the enemies in the bar first and get them to follow you to where the alcohol is located. Then quickly drink three bottles by highlighting them and pressing SQUARE, before killing as many enemies as you can before the effect wears off.

This is the one trophy I would recommend restarting checkpoints to farm, as unlike the other kill-related trophies, there are very limited opportunities to earn this one. The following video shows this method in The Graveyard Shift in Shantytown:
