I feel like the game could benefit from a couple new Biomes. While not all would fit in Navezgane, I feel they would be good for random gen. Some ideas: Beach biome, Swamp Biome and Volcanic Biome, and Frozen Biome. I could go on, but I have ideas with these biomes. The Beach biome would have cheap/luxury hotels, aquariums, waterparks, restaurants and harbors. The stuff you'd expect at a beach. As well as palm trees and sand. This biome could introduce boats. And maybe a water threat, such as sharks/zombie sharks/piranhas, or a special swimming zombie. This could also introduce a fishing mecha
