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 herself, 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.

Gameplay
Sword Art Online: Infinity Moment simulates a virtual reality massively multiplayer online role-playing game (VRMMORPG) Sword Art Online. The player controls the on-screen player character, Kirito, from a third-person person perspective. Within the game, players explore monster-infested fields and dungeons.

Players can attack monsters in real time. The player only directly controls Kirito, while the other characters are controlled by artificial intelligence. Players can issue a simple command to AI controlled characters (recover, defend, switch, etc.). Sufficient SP is required to use skills. Kirito will gain small amount of SP from each attack landed on target and large amount of SP from a successfully parry.

When a boss room is found, after fulfilling all the requirements, the player can initiate a boss raid and a party of up to eight people will be formed (Kirito, his partner, and other candidates from other guilds).

On 76th Floor, Arc Sophia, the player may restock on items, customize their appearance, buy equipment, or chat with other players. The player may also undertake optional quests.

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. She tells Kirito that 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 sexually 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 from the scene. 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 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. Kirito can not let this go and request another duel with him. This time Alberich's status is very high, far higher than Kirito. However, Kirito proves to him that high status alone can not beat him. Alberich escapes after his defeat, but later his subordinate is captured by Kirito and Klein and Kirito interrogates him. The subordinate then leads Kirito to where the disappeared players are sent to. Kirito finds what seems to be a research on peoples' feelings and a research record. He notices that the days written in this record are the same days when Strea has a headache. Kirito recalls that when he first met Yui, she had broken down because of players' negative feelings. He believes there is a connection between Yui and Strea, therefore he decides to destroy all the research data.

After defeating the 98th Floor's boss, Alberich appears before Kirito again. He tells Kirito about his scheme, a research on the manipulation of the human soul. His identity is also revealed to be Sugou Nobuyuki, who works for RECTO Progress. Alberich also explains that he has high level stats and strong equipment due to using a super account. Alberich intends to kill everyone who is in his way and he starts by paralyzing all the players and summoning «Hollow Avatar», the 100th Floor's boss, to assist him. However, Kirito breaks free from his paralysis status and defeats the boss. But, before he could reach Alberich, he is paralyzed again and Alberich takes out a weapon which can turn anyone's HP down to zero with one strike.

Multiple Endings/Epilogues
The game has seven different endings -- a generic ending and six character endings.

Trivia

 * The Guilty Scythe boss has a very similar design to The Fatal Scythe, which appears in the SAO anime. The Rebellious Eye and the Genocide Eye also have designs similar to The Gleam Eyes.
 * All side quests, including main character side quests, can be done in a single play-through; as such, the player can essentially choose the ending he wants to experience before the last boss fight.
 * You get to fight Alberich for the second time in the game on Floor 97 and he is at level 200, even higher than Heathcliff on the last floor. However, he is really weak, having no combat experience.
