Shelter is a popular zombie game that has elements of a collectible card game as well as a castle defense game. In the game, you need to work your way through the city, battling zombies, in an effort to be reunited with the woman you love. As you go along, your card deck grows and the challenges increase.
Shelter is not your typical zombie game, and the combat is more strategy oriented than action packed. You are defending against the zombie onslaught through a card game and not running around shooting them. Unlike most card games though, the game offers deep and challenging gameplay that gets very addictive.
