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!

Could have a better combat system such as not so long animations. Our partner could have been auto-randomly-generated (in appearance) so no one also had the same "koharu". Summons are too expensive. Appart from that, allowing us to create our own char and have this many skills was cool. Crafting system seems interesting.

The gameplay is amazing and the storyline extremely good, I really enjoy just reading the dialogues of the characters (please consider fixing some typos, up to 7th floor at least). Some connectivity issues here and there causing sometimes the impact of your or the mob's hits to be delayed, pretty annoying considering they hinder your dodging too, but other than that this game deserves a solid 5 stars.

As a Sword Art Online fan, this game is one of the best that I have ever downloaded. The gameplay is crazy. It is not laggy, and the fact that you are playing in the same world as the other players and can interact with them makes it super immersive. If you don't know the original story, that is not a problem. If you want to pass the game with friends or alone , no problem either. Also, the graphics are amazing and beautiful. The combat system is great, too. JUST DOWNLOAD IT.
