Sword Art Online: Infinity Moment

Sword Art Online: Infinity Moment (ソードアート・オンライン -インフィニティ・モーメント) is a game for the PlayStation Portable (PSP). It is set in an alternative Sword Art Online storyline. The game is made by Namco Bandai Games, Criware Games, Banpresto, Matchlock, Bishamon, and developed by Aquria.

Prologue
"I'm sorry, but I have a request."

"What is it?"

"I don't plan on losing. But if I die here, I want you to make sure that Asuna can't kill her self, even for a little while."

"Very well."

''This isn't a duel... We're fighting to kill. That's right. I'm going to kill him!''

The game starts at the point where Kirito and Heathcliff are fighting against each other to the death. After a cut scene, a tutorial starts. You get a chance to fight Heathcliff until his health drops to the red zone which triggers another cut scene. Whilst Heathcliff is about to finish off Kirito, a huge glitch virus in the SAO Server occurs and interrupts them. Kirito uses this chance to defeat Heathcliff. He then notices that the SAO Server is still keeping them in the game, preventing them from logging out and realizes that the real battle is on the 100th Floor of Aincrad. It seems that the glitch virus in the SAO Server wants to take over the last 25 floors of Aincrad.

Story
After the prologue, everyone decides to proceed to floor 76. Many irregular phenomenons happen one after another, such as earthquakes, all skills and items data being corrupted, etc. They also find out that the Teleport Gate cannot bring them down to Floor 75 or any other lower floors anymore.

After the defeat of the Ghastlygaze, the 76th Floor boss, Kirito meets Leafa, who turns out to be his little sister. Some kind of error sent her here while she was playing ALfheim Online. Right after that he meets Sinon, who mysteriously falls from the sky of Aincrad.

On his way back from a dungeon on Floor 80, Kirito meets Strea, a cheerful girl who has been following him around since Floor 79. At first, Kirito is wary of her, but as they spend some time together, he begins to consider her as an important friend. Strea is always found being alone, like a solo player. From time to time, Kirito finds her acting strange, saying "I must protect this world so that it won't disappear" and having a headache as they advance to a higher Floor.

There is a new group of strong players who wanted to join the Clearing forces on Floor 85. Kirito notices that something is wrong with them and decides to test their abilities. He has a duel with their leader, Alberich. Alberich is indeed powerful, probably has higher status and stronger equipment than Kirito. However, he doesn't have any skill or combat experience. Therefore, he is beaten by Kirito and is rejected to join the clearing group. After being rejected, the group is continually found causing troubles for other players. They can eventually bypass some rules of the game. For example, they can sexual harass other female players.

Before the fight with the 90th Floor boss, upon entering the boss room, Strea has a headache again. Kirito decides to finish the boss as soon as he can and rushes over to see her condition. Strea's personality suddenly changes. She faces Kirito saying she won't allow him to clear the game and she disappears. Start from Floor 92, Strea is found powering up the boss before the fight and disappears before Kirito could have a conversation with her.

Another strange incident occurs. Players are disappearing mysteriously. On Floor 97, on his way to the dungeon, Kirito hears Klein's scream. He finds Klein, Alberich, and another player lying on the ground. Klein demands Alberich to put away the suspicious weapon, a dubious design knife, in his hand. Alberich refuses to do so and uses the weapon to stab the lying player's body, causing him to disappear.
