Uncanny Valley

Steal Buck's car, then essentially reverse your steps all the way onto the train. Basically you will "win" by saying "screw this" and running away.

After completing your training day, return to your apartment and sleep. After waking, immediately go to Buck's room on second floor, room 6 of the apartments. Take his car keys and go to the facility. Interact with the car to get taken back to the train station. Enter the train station and move all the way left to enter the train. The ending will start.

Do not go back to bed during day two. Go to the facility and the power will eventually go out. Go to the generator located to the right of the entrance to the apartments. Go inside the hut and interact with the generator to rewire it. Then, finish your day and go to your apartment and sleep. When you wake up, you will see a red light. Use the fire extinguisher taken from the ground level kitchen to break the door open. Take the safe key from the wall. Go up to the floor four and enter room 4 to get the key card. Go to the facility and go to the fourth floor. Move all the way to the left to the safe. Interact with the safe and you will automatically use the safe key. Enter the code "1972". The safe will open and you will get the other key card. Go to the ground floor and use the second elevator to reach the lower levels. Move all the way to the left and enter the freezer. You will find a dead frozen Buck. If he does not appear the first time, exit and re-enter the room.

Use the following steps. Note: Do not become friends with Eve. Get both key cards and go through the lower levels (second elevator). After reaching the third floor of the lower levels, attach an Android Reconfiguration Device to an android. The android will open the systems door for you. You will now see a large garage door. Go through it to reach the back of the warehouse. Go outside of the facility and notice that Buck's car is gone. Go to the left, exit through the gate, and watch the ending.

Step 1: Always check in with Buck before beginning your shift. After waking up, go directly to the facility and enter the monitoring room to find him sitting on the ground floor.
Step 2: Speak with Eve on your training day to befriend her. She can be found on the ground floor lobby. Do not leave before the dialogue ends. You also have to meet her in the relaxation room on floor two, left door of the facility on your first day, after she leaves the note on the inside your door.
Step 3: Fix the generator on day two.
Step 4: When you arrive at day four, go to Buck's apartment which is at room 6 on the third floor. Take his car keys. Then, check in with Buck at the facility as usual. Immediately leave and take his car. You will get into an accident with the gangsters.
Step 5: Escape from Eve and the lower levels then go outside of the facility. Buck will speak to you from out of nowhere. Keep moving to the left, all the way to the train station.
Step 6: Eve will appear at the train station. Ignore her and enter the train station to catch the train.
