Bests & Worsts Reviews from Amazon

When I first heard of Heads Up! we immediately downloaded it and had a lot of fun, but it faded fast due to the limited free decks. Now with Amazon Underground, all of the expansion decks are free!! There are 30 expansion decks that normally would have been $0.99 each, but there is a line through each one and you can just play them directly. The additional decks were: Adult Supervision Friends (the show) Rhyme Time Bad Behavoir Anatomically Correct Express Yourself Mix it Up Video Game Land Icons, Legends & Stars Block Buster Movies Hey Mr DJ Perfect Pairs Hip Hop Super Heroes Branded Food Fight Movie Buff Favorite Fictional Characters Wish You Were Here As Seen On TV All the Right Moves I'm With the Band Sports Legends Totally 80s Thats so 90s 70s Fever Broadway Baby Take It Literally Act it Out - Sidekick So, with $30 worth of free expansion decks, it this Underground thing legit? Is it for a limited time? Did I sell my soul to the devil? I dont know, but in the meantime, anyone want to play Heads Up!?
