Nice...
this flash was purely and epically amazing, and the cliffhanger was just as good as a Romero cliffhanger. But there are two unanswered questions: 1. who did the chick shoot? herself or the Main character? 2. What happened to those other two guys?
All in all, a great flash and I hope you make another!*
*how the virus was made/released, or what happened to the other two guys? (just suggestions)
