About this game

"Sword Art Online" MMORPG is here! "Sword Art Online Integral Factor (SAOIF)" is an MMORPG in which you enter the world of SAO and aim to conquer Aincrad with Kirito, Asuna, and other SAO characters.

“If it were me, would I have been able to change that reality (Death Game)?”

■Story

2022 “Sword Art Online” is the first full-dive VRMMORPG developed by genius scientist Akihiko Kayaba.

However, the whole story was a terrifying death game in which you could not log out until you cleared the game, and game over meant death in the real world.

This is your own strategy story as you aim to clear the game as one of the players trapped in the death game.

■SAO MMORPG with an original IF story!

An MMORPG where you can enter the world of SAO and relive the encounters with Kirito, Asuna, and other SAO characters in Aincrad, and their relationship with the original story from your own perspective.

You can experience an ``IF story'' that could have happened in the ``Aincrad'' that you are involved in. There are behind-the-scenes stories that are not depicted in the SAO original, and developments that are different from the SAO original!

Let's conquer the vast field of "Aincrad" with the SAO characters, their partner "Koharu" who is trapped in the death game, and friends from all over the country who are connected online!

■Only available in online RPG! Cooperate with players all over the country!

Collaborate with players from all over the country to conquer powerful monsters and difficult quests!

Unique to online RPGs, you can form a party and take on the boss together, or join a guild and exchange information in the guild room. You can experience an "SAO MMORPG" where you control your own avatar and conquer Aincrad with your friends.

■Adventure with SAO original characters! "Assist character"

Form a party with original SAO characters such as Kirito and Asuna and challenge the fields and dungeons together! Friendship levels and levels are set for each character, and you can customize SAO characters to your liking by changing costumes and setting skills.

■ Master your skills and weapons! "Battle System"

Use your skills and weapons to survive the death game! In order to fight against powerful monsters that appear as you progress through the levels, you can produce weapons and equip skill records with various effects.

The key to conquering Aincrad is to prepare for your opponent's weaknesses and attack patterns and consider combinations of weapons and skill records.
