why game cant be purchased?

Hi, does anyone want a copy of the dlc for this game? i will trade it for some cards or gems

I figured a brief 'eh' game for $2.50 and I bought the four spare helicopters with a spare dollar so when I started playing it I started to really enjoy it.

the way to restart game at 0 ? someone is able to help

Hello, do the Albatross Chopper, Arrowhead Chopper, Night Avenger Chopper, Ostrich Chopper appear in the Zombie Zombie Zombie campagin or is the Zombie Zombie Zombie DLC separate to the main game and the Chopper DLCs? Thanks
