story related and cannot be missed.
A short way into the game, you'll find Roy in the kitchen for the second time, after the crap has hit the fan and everything has gone to hell. Shortly after this, you'll be back outside the rig with a life boat dangling beneath you.
Make your way along the linear path to the second life boat.
- Remove the pin from inside the right hand strut
- Remove the pin from inside the left hand strut
- Go the the right side of the lifeboat crane and release the lever
The life boat will launch, and your achievement will unlock.
