Base Defense is a tower defense game in which you use different types of weapons to try to stop enemies from destroying your base.
You can completely improve these guns by using gold coins and scrap metal from dead enemies. Make sure to buy new things like gunners, sentries, triple shooters, and even axes that you can throw when they become available. It is a lot of fun to watch your machine helpers do all the work while you plan your strategy.
Have fun and good luck!
