I figured that I'd throw up a comment and say that this probably my favorite game to GM of all time. The book is written expertly, and gives the GM tons of mechanics to sink into that make GMing super easy and low prep compared to a lot of games (Looking at you, DnD). It's powered by the apocalypse, and as such, it runs well via online play.
Even if you don't think you can sell your players on the theme, check the game out anyway, there's tons of awesome stuff to crib for your other games (the concept of clocks, downtime action suggestions, steal a whole faction if you wanna)
