Yep, this is definitely Sword Art Online. All the angst gives it away. And the swords.
Bandai Namco has released the opening movie for Sword Art Online: Alicization Lycoris, and it's just about everything that you'd expect. Catchy, punchy Japanese pop rock, cool-looking shots of main characters, and a lot of pretty animations.
The action RPG is still on course to release later this month, on the 10th July. Will you be training your sword skills until then? Activate your most powerful attacks in the comments section below.
