- "Make it through "Night Life in Bright Falls" in one go, without dying or restarting even once."
- "You fought your way through the streets of Bright Falls without getting killed."
Load up Episode 5, the first chapter, "Night Life in Bright Falls." If you prepare and don't waste powerful weapons, then there aren't many tricky moments. The two potential tricky spots are:
The church and fire station defense. One mid mission and one at the end. In order to unlock the achievement you must finish it, from the police station to the helicopter, without dying or restarting. Just make sure you load up on all the equipment before you move to close to Sarah and Barry. Otherwise, the Taken come. If you scavenge the lot before hand of both areas, it should be easy.
The helicopter - You're on your own here. Just use the flashbangs wisely, shoot the gas canisters to save flash grenades, and try to turn on the lights whenever possible. Stay on the pad as well. If you stick to that strategy, you'll do fine.
