Ever since the first attack, people and animals have been mutating into Godzilla mutants, who are all carnivorous and super dangerous. And there are living pieces of Godzilla's flesh roaming the cities, some just slowly moving blobs, some almost fully formed into a small replica of Godzilla. Be careful of what you eat, it may be tainted by Godzilla radiation. There are other giant monsters like the friendly biollante, rodan, and mothra, or the dangerous hedorah (or the unknown hydra, ghidorah).
