Born in Bristol to a military family who moved to Londonderry when his father was transferred to the Ulster Defence Regiment, Cooper wouldn't see a whole lot of the conflict in Londonderry but his father had told stories. Come the outbreak, England would be hit fairly hard, especially in 2018 when the a dirty bomb was unleashed from an Irish Separatist group from Chernarus. This bomb would unleash havoc throughout the UK and this was seen firsthand through an IRA attack on Coopers family with his father being killed and his mother being kneecapped and left to die. After these events, Cooper would sign up to a local cell of nationalists made to protect the town of Londonderry from the threat of infected and terrorists that had surged in popularity in the south. Eventually Cooper would be sent to Chernarus apart of an attachment in order to find those who made the bomb.
