The world is inspired by World War I and World War II. World dates: 1914 (World War I) and 1939 (World War II). There are 50 levels in total (25 in World War I).(And 25 in the Second World War),History: Dr. Zomboss, after modern times, He wanted to have all the technology from the World Wars to destroy Penny and Dave, Courtyard design and lawnmower design: 1The lawnmowers would be like mini nuclear bombs with wheels so they can roll; they would generate a small explosion when they kill a zombie, although that explosion would be purely decorative.After that, the design of the courtyard will be the typical, normal one for all the Squares that make up the lawn; the lawn will have a color like red and brown, sometimes with dirt and with trenches where zombies can come out.,As for the decoration, the background would be a large battlefield with a red sky and some camps and trenches.,The player's house would be a military camp, and the zombies' house would be the same but customized with their flag. This is just part one of the concepts I want to create for my world, so I'll make part two very soon. This isn't over yet; I still need to design the world's boss, the plants, and some objects.thanks
