Fans of classic Fallout may remember one of the game’s most distinctive features: the time limit. The inclusion of this mechanic makes perfect narrative sense; in Fallout, you were chosen by the overseer to look for a replacement water chip for your community of underground vault dwellers.

In short, you’ll need to finish the entire game—from finding the water
