Sword Art Online: Integral Factor is a mobile MMORPG based on Reki Kawahara's Sword Art Online series.
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!
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!
