About this game

The newest Sword Art Online game!

This time, the protagonist is...you!
You appear in this online RPG as a member of an Assault Team, working with other imprisoned players to reach the 100th floor of Aincrad!

What if you were trapped in a game of life or death?
You can experience meeting familiar characters and connecting to the original SAO story from your own POV.
Experience behind-the-scenes stories not seen in the original SAO, and completely different story developments! Live out a "what-if" story where you affect Aincrad!

Battle System
Fight through the sprawling fields of Aincrad with your partner Koharu, trapped together in a game of life and death!

You'll need to cooperate with Assault Teams across the land and battle together to beat powerful monsters and tough quests! Forging stronger weapons, using skills with all kinds of effects, and preparing for each enemy's weak points and attack patterns are all key to your success!

I've been playing this game since release, and it is amazing, there has been constant content updates. Yes, it looks a bit outdated for a mobile game, but otherwise, all of its functions are dynamic. The gacha is very rewarding, and you get far more gems for completion than I find in other games. As far as the story goes, if you're interested in SAO and actually want to read,you'll love it. Or theres just a skip button, y'know no judgment. It's a good mobile rpg by itself, give it a try!

From what I know, the game has been out for 8 years. In that time it seems they have refused to touch the static and completely uninteractive feature that is combat/mobs. I have not been hit once because the mobs won't do anything until after you hit them for a couple of seconds... It's basically a dress up simulator disguised as an mmo. everything feels lazy and outdated. Nice artwork though

so unfortunately, I lost my save data and had to restart. lost a lot of gear. Completely my fault though, not the games. new phone and didn't transfer properly. However, I'm actually excited to start fresh. now I can see how the game plays and compare to how it was. very good game, honestly 100 times better than other payed games like ones on switch. very enjoyable. I will continue to play for years to come.
