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!

An interactable visual novel with dialogue options that have no impact at all, thrilling quests such as "kill this random enemy (literally) 100 times", loading screens that make up at least 15% of my total playtime and a story thats gets put to shame by most characters blending their bland personalities together. They got the assets but definitely not the essence of SAO, the only thing I can personally recommend is the skill customization, which is sadly restricted to gacha for the most part.

I love the storyline and mechanics. Downside is the heavy grinding (this one is acceptable) and skill record rate. Edit : The game exist almost 8 years now, but gacha system still sucks. My long time friend just quit today, we played together for 5 yrs. He did 10 rotations (62.500 AG) on Yuuki's BD banner, didn't get the new Burst skill. Pls just give us a way to pick specific 4*skill, like give us 1 banner stone for every 10 pull and we can exchange 10 of it for specific skill from said banner

story is fine and all, but lads, there is a limit to how much reading is too much. more than 75% of the game time i spend reading through conversations or clicl through all the menues. its awesome how much stuff you throw at us so we got something to do outside of fighting but.. sometimes i just want to fight something. i reached a point where i just skip through all the conversations, and still spend the majority of time in Conversationscreens. this is not a manga or an anime, this is a game.
