Think Fallout (any of the games) meets Jeremiah meets Thunderdome & a touch of Eli...whip it up with xenosludge into a slurry with a side of Escape from LA and Zombieland & some good old fashioned alien unknown 195-60 genre conventions ... Ya!
Quick paced, nothing really new. Though the return of old B-movie and PA is comfortable, having everything piled in with zombies is a bit much.
A decent entertainment and beach read for enthusiasts of all the above. If it was a movie, Rifftrax would love it!!
