Balloons vs Zombies 4

This world is for the livings, not for the dead! Zombies are not welcome here and you need to explain this to them. Grab your weapons and get rid of the invaders as soon as possible!

What would you do if there was a zombie apocalypse outside? How would you act and what weapons will you use? There won't be an access to the most advanced weapons and you will have to use something much more simple. Look at the weapons available for you and use them to kill zombies and save people who were attacked by them.
