"Cytus II" is a music rhythm game created by Rayark Games. It's our fourth rhythm game title, following the footsteps of three global successes, "Cytus", "DEEMO" and "VOEZ". This sequel to "Cytus" brings back the original staff and is a product of hardwork and devotion.

In the future, humans have redefined internet development and connections. We can now easily sync the real world with the internet world, changing life as we have known for thousands of years.

In the mega virtual internet space cyTus, there exists a mysterious DJ legend Æsir. His music has an irresistible charm; people fall madly in love with his music. Rumor has it that every note and beat of his music hits the audiences in
the depths of their souls.

One day, Æsir, who had never shown his face before, suddenly announced that he will be holding the first mega virtual concert —— Æsir-FEST and will invite a top idol singer and a popular DJ as opening performances. The instant the ticket sales began, an unprecedented rush occurred. Everyone wanted to see Æsir's real face.

On the day of the FEST, millions of people were connected to the event. At one hour before the event started, the previous world record for most simultaneous connection was smashed. The whole city was on its feet, waiting for Æsir to descent from the skies...

Cytus is back!


Not that it ever left in the first place. I’ve been an avid fan on Cytus since it was released way back, before it even had chapters, and still love it to this day as my favorite mobile rhythm game. Now we have Cytus II, which doesn’t make too many changes to the base formula, while adding a Twitter like story telling element and different characters to level up. I love it, and would love to give it a full five star rating, however even on newer devices like the 2017 iPad, along with the older 6s+, the game has a bit of frame rate issues. I’d say a stable frame rate is a high priority for a rhythm game and the old Cytus held perfectly across all devices. I’d also like to add that the new notes are very flashy, perhaps a little too much so. It’s a bit distracting and unless they’re just images, they’re probably one of the causes of the frame rate problems. It would be nice to see an option for less flashy notes, and frame rate stabilization. Despite being a big fan, I’ve never purchased any IAPs in Cytus and have always wished there was a way to unlock them through progression rather than money. I’d of gladly payed a larger sum for the game itself for all of its content and splitting up the bill. Besides that, I can see this game delivering many hours of fun and can’t wait to see it grow and improve!



So far I enjoy the variety of backgrounds more from the first Cytus but overall this game is amazing. It deals with some of the oddities of the original Cytus in creative ways. The really fast moving reaction bar prevents me from not seeing the notes that would appear under my thumb/fingers (depending how I'm playing). You can also tell that Rayark has used lessons they've learned from Deemo and VOEZ when it comes to mapping the notes and adding variety. The maps feel more natural than in the original as well. I'm enjoying the story so far. I'm not done with it yet although I'm not sure if this a sequel or prequel at this point. Idk when I'll buy the other characters but it really does seem like it would be worth it. Can we get the million downloads challenge again ;) ?

Edit: you unlock more levels as you play, it's not 9.99 for 3 songs. I'm pretty sure they'll be adding songs to each character too as time goes on so I'm sure the initial purchase of 9.99 for 10-11 songs will gain value when more songs are added. Then original launched with 30 I think. This one already has like 55 so this will be exciting!

Rayark doesn’t disappoint!


Improvement in almost every aspect. We’ll get to that almost later, but first, the mountain of good things.
The story actually matters and is so good! I’m not usually a fan of mystery or who done it themes... this had me hooked. Granted, this isn’t the first game to use social media as a story tool. It’s just the best example of it done right I know of. The songs are fun, the art is spectacular, character designs are memorable, and dynamic scanner speed is a stroke of genius. The game as a whole is a delight.
As for that almost... the number of songs is kinda light. In of itself, that’s not too bad, but it makes getting the next bit of story feel like a grind going through the songs a second time in this sitting. Changing characters combats this, but I still wish it didn’t even come up. On the bright side it’s something that can easily be addressed in an update and it didn’t keep me from enjoying myself.
I’m more than happy with this game and can’t wait to see what the team does with it in the future. Please port to the switch and let me give you money.
