Zombies Ate my Motherland

The zombies have taken over the world.  One day while you are hiking, a zombie attacks you.  Fortunately, you are lucky enough to getaway.   You have settled in a farm and found out that there is a tractor that you can use for your escape.   However, the tractor is broken and you will need a few parts to complete the tractor. The game is played via mouse and keyboard.  You will have several weapons as you progress in the game, but you will start with just a gun.  The crates will give you the parts that you need.  Try to get to your home so that you can use the parts that you found to repair the tractor.
