I would die. In a serious situation where things went down as they did in the beginning, nobody could prepare for how they would react. You could be as prepared as can be, and caught out shopping away from your arsenel..and trip on a shoelace. And bam, a fellow shopper is wearing your intestines as a hat. Because that's what the infected really want.
Since someone brought up Borderlands, I would build a sniper's tower and pay Mordecai in booze to snipe all of them, giving me a better chance of survival. I mean you guys saw what he did in the Preserve area in Borderlands 2, right? After a certain unfortunate event...
I think I'd also steal the technology from Hyperion and "Go Turbo" and bring it into our world and have that kick **bleep** fence only a small, annoying robot could deactivate(love ya Clappy)
"I heard someone got executed today" "Really, what for?" "Uniform violation I **** you not."
if it was me I would honestly die, im very delicate for some reason, I get dehydrated really quickly, get fatigued, and the worst is that my contacts need constant care, because without them im pratically blind, I guess id make a good clicker
In short, yeah, I'd survive.
