The popular Zombie Attack game from Smarter Apps has been updated in anticipation of Halloween, this time adding 50 new levels - bringing the total to 250 levels of play. The zombies are sporting their new Halloween costumes but are still as hungry as ever. Use your rocks, grenades, fireballs and more to take out the masses of brain-eating zombies. This one is great fun and will keep you busy as you count the hours until October 31st. Zombie attack is available for most devices from BlackBerry App World.
