I'd be the guy who uses the short time available to me to rescue as many of my loved ones as I can, then lead them on a journey to the safest place possible, which around here is the Aran Islands. Unfortunately my girlfriend lives on the outskirts of the city and I'd have to go into the heart of the madness to save her, so if I was to meet a tragic end, it'd be early on in the outbreak.
With that in mind, there should be an option for the guy who gathers his friends and family together, and co-ordinates them to use their best skills and work together to survive, lets call it the group leader.
