Missable achievement within a story environment.
*** Spoiler - click to reveal ***Towards the later part of Chapter 11, the Irish destroys your house. Joe and you decide to get even by raiding their hideout. Kill the whole lot (grab the shotgun from the bartender and the grease guns lying around to make things easier).
Once everyone's killed, the Irish leader will try to escape in a car. Instead of engaging in a car chase, either:
- shoot the tires on his car to stop him from driving away, and then kill him; or
- shoot the gas tank of the car to kill him immediately.
The achievement pops upon his death. Take note that if he drives away and you fail the car chase, the story will still progress, but you'll not get the achievement.
