Scenario: #12 - T-Rex Showdown
This is the last scenario of Episode 1. You will be attacked by the T-Rex at the visitor center. When it shows up, you will have the option of pressing to control the father or for the daughter. As Jessica (the daughter), move to the left two screens when the T-Rex is on the opposite side of the pillar when it's trying to find you. Now, switch the the father and push a crate on the T-Rex. You must do this before time runs out, but you are given plenty of time.
When escaping on the roof, Jessica will be hanging for a brief moment. She is hardly a story high and is told to let go but she is scared (maybe not seeing how low to the ground she is). This is when you want to make sure you tell her "Don't be stupid" to grab the World's Best Dad achievement. You will then make a call on the radio and ask to have the car moved. This will end the episode.
