If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
It is an apocalyptic world again and you need to save the world by driving an ice cream truck, carrying the antidote from humans and pets turning into zombies. You have to always keep it cool and take it to the Lab. The zombies will attack you so you have to protect yourself by shooting them down. Collect power-ups to help you and coins to buy upgrades between levels and improve your truck. Have a lot of fun playing this cool game!
