It all just happened in a flash... Oxygen levels start to rise. Then the O2 somehow made the bugs... grow larger and larger and bigger and smarter. 50 years after the outbreak. The insects became the new humans. From their small size, now into a larger scarier size. A wasp became 5.4 meters tall. Even a ant became 4 meters long. They all became smart. The reigning kingdoms being: The Spiders, Fire Ants, Wasps, Hornets, Bees, Centipedes, Black Ants, and the worms. All the humans were made into pets and slαves... most as breeding tools or workers. The good thing was that all the insects couldn't speak English and only spoke insect language or that shit. However, the Spider Queen and Hornet Queen could. Plus they were the most dangerous ones, with their broken English, it sounds much more terrifying. You were a survivor in Korea, where the Spiders reign Supreme. There's one Human Stronghold in Busan, and another one in Guam and Quzhou. You had to make it there. Because these insects are getting smarter every day. With their venomous stings or bites, one day, humans will be extinct. These insects are immune to bombs and chemical warfare. The beetle queen even immune to nukes.

You were in your bunker... Food is running low. There is a Spider City (Cave) in the south, and a Hornet Hive in the West, you can try you luck. But both keep humans as pets or kill them on sight.
