Ok, cool. Slow ish. So I can't just go at a brisk walk and be faster. Cool that will make things interesting.
Although. I'm was basing most of my ideas by "the zombie survival fuse" and "world war Z" the book, not the movie. Which was like 6-12 hours (maybe days depending). 5min seems excessive but 1-2 hours I can work with.
Cool. Thanks for the clearing up.
