Build or be Killed

Build or be Killed is a solo zombie-themed solitaire game where you play as a survivor trying to build a barrier of cards around a zombie-infested city to keep it from being overrun. Throughout the game, you will be collecting cards to use as weapons to remove zombies from the city or to use as barriers to place around the city. Manage your collected cards well or risk the city being completely overrun and losing the game. —description from the designer
