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!

Fantastic game which makes you feel like you really dont need to spend any money to progress. Plenty of opportunities to get the premium currency without spending money. I'm happy to play this for half an hour at a time or a few hours, can just pick up and play. Brings the SAO universe to life just enough to satisfy that itch. Definitely recommend.

Can't actually get past the loading screen. It seems that this game isn't compatible with a great deal deal of Android devices, really disappointing as I have wanted a game like this for quite a while EDIT- I have gotten a new phone that can run this game. It was a case of the software on my old phone was too old, therefore it was unable to run the game.

Decent enough game, just seems overly complicated. You collect achievements, then have to collect it again from your in box, you summon things and doesn't tell you how to use them. Tutorial is way too long, and I just want to explore not be talked to death. Don't think this game for me really. Though you might like it?
