What the developers have to say:

Why Early Access?

“A 3D action game is very hard to develop for only a handful of people. The original demo alone cost us 9 months to make. Although it attracted a lot of attention on the Internet, the demo was entirely free, so we didn't really gain anything from it. Our team was not very stable and we didn't get any help either. But, for the dream I have for over 10 years, I simply cannot give up even with no help. So we started U-Secret Studio, which is less than 1 year old now, we work from 7am to 11pm every single day with no rest at all. So we decided to EA it first and design the following chapters that are not in the EA version with the feedback from the gamers.”

Approximately how long will this game be in Early Access?

“6 to 12 months.”

How is the full version planned to differ from the Early Access version?

“We plan to complete the features below
◇6 to 8 hours of playtime, 15 levels.
◇Better optimized
◇Smother and more intuitive gameplay
◇Better animation.
◇Multiple rounds of gameplay with collectibles.
◇Optimized models
◇More collectibles.
◇Better localization.”

What is the current state of the Early Access version?

“◇8 chapters in 7 maps, 3 to 4 hours of gameplay.
◇36 types of enemies, 2 epic boss fight.
◇Aerial combo, execution, CQB technique and scarring are all supported.
◇5 outfits and 2 weapon skins can be collected and used for free.
◇Hardcore Minigame.
◇4 Difficulties
◇3 Weapons
◇Full Japanese voice acted
◇Fully animated cut scenes”

Will the game be priced differently during and after Early Access?

“◇No, the price will be the same. But you'll find outfits more easily in EA version.”

How are you planning on involving the Community in your development process?

“We plan to let all gamers who are interested in this game participate in optimizing this game. That means Steam community, both discussion and reviews will be one of the source we receive feedback. Gamers can also contact us by sending an email to uhome@u-secret.net, we'll listen closely to the community and power through with everything we've got.”
