At some point in your playthroughs, you will encounter Zoe in a car sequence which leads to this event happening, where she is captured by the police and they stop at a gas station at some point down the line.
For me, this occurred on the second teen play through and I didn’t get the gas station sequence until the third one. But note that the event itself is scripted, it may just happen in a different order.
Once you find Zoe handcuffed to the police car, speak to her and free her. You start this by going around the left side of the gas station. You can either:
— Break the antenna tower, you need specific skills to do so (I did not have these at the time).
— Commit arson by the antenna tower. Get a hose and a empty gas tank from the rear of the gas station. Go back to the police vehicle and drain the fuel from it. Go into the gas station and buy a box of matches for $2. Go the back left of the gas station to ignite a fire.
Once you’ve done either of these two, DO NOT run back from the way you came as the cops head that way. Instead, go the other way where the cops initially were. On the table where the cops were sat, will be a set of keys. Pick them up and head for the police car, open up the police car and pick up the handcuff keys, then free Zoe.
The achievement will unlock after this.
