Terms and Conditions
Reading the terms and conditions, it looks as though the offer started rolling out in April and goes through until December. I only received the email today.
The offer is targeted and only for select PlayStation Plus accounts, and it is the full game. You must opt in to receive Sony marketing emails to receive any of these Sony promotions.
