Nido: Apocalypse

A decade old MMO RPG video game based on Earth. The entire map is a 1:100 scale version of Earth abandoned by normal civilization but filled with new humans. World is filled with monsters from both fantasy and Syfy setting: this is Nido. Each dlc/update changed some aspect of the game.
Nido: Awakening was the video dlc/update. Releasing a sleeping AI bent on destroying the world. Players had to guild up forces to defeat such a wicket creature.
After 10 dlc/updates Nido: Apocalypse was said to be the last update of the game.
William and his friends in the Guilded Losers wanted to hope one and play this last update together as they spent the last decade playing this game.
Upon the release of this update something happens causing them, and countless other players, to be sucked into the game without an escape.
How will they ever return home? Or will they chose to stay in a fantasy realm?
