Windows Open Beta answers.
Buy on this website or inside the game with the same Katana Inu account. Combat and saves work offline; leaderboards, account features and purchases need a connection.
Buying & ownership
Where do I purchase something?
Two ways, one account: buy on the purchase page with your Katana Inu Launcher account, or open the Shop inside the Windows game. Connect the same account in the game and the purchase is there. Contents and prices are the same.
Which payment methods are available?
Pay by card through Stripe or by crypto invoice through NOWPayments. Every listed price includes statutory VAT. Stripe applies the correct tax treatment for the selected country and shows the final total before payment.
Which $KATA counts for the holder benefit?
Only $KATA in your own wallet counts. Funds on exchanges do not count.
How do refunds work?
Contact business@katanainu.com with your receipt. Withdrawal and statutory defect rights are described in the Terms.
How do I restore a purchase?
The purchase is linked to your game account and device. Use the in-game restore option or contact support with your receipt if access is lost.
Game & fairness
Is any of this pay-to-win?
No. Cosmetics change no combat stats. Hero packs offer new fighters with the same class values; the storage expansion is convenience.
Does the game run offline?
Combat, saves and progression run locally. Leaderboards, seasons, world boss, purchases and restoration need a connection.
Is Samurai Task Force free?
Yes. The game is Free to play; optional packs contain heroes with equal class stats, convenience, and cosmetics.
Why does Revive become more expensive?
The price follows the income of your best reached league and rises after each use, capped after four increases. Home shows the current five-price ladder. See Combat and Revive.
Is equipment gone after I sell it?
The last 20 sold items remain in Sold and Local sales. You can buy one back for its sale price. See Inventory.
How many pieces can one fighter equip?
Three: one Blade, one Guard and one Charm. See Inventory.
Technical help
What does my Windows PC need?
At least Windows 10 (64-bit), 1 GB RAM, OpenGL 3.3 and about 1 GB free storage. Windows 11, 2 GB RAM and 2 GB free storage are recommended.
How do I report a bug?
Open Menu → Report a Bug in the game; it is also available in Settings. Describe what happened and what you expected. The form attaches the last game image; you can also select another PNG, JPG or WebP image up to 2 MB. Version, league, level and platform are added automatically. Offline reports stay on your device and are sent later.
If the game will not start, email business@katanainu.com with your Windows version, game version and error message. Please do not attach passwords or payment details. Privacy
How do I keep a game window in front?
Click the battle strip to bring its open windows forward. They step back when the game loses focus, so they do not stay over another program. See System and window behaviour.
What if the automatic update does not finish?
Choose Download from website in Settings and run the current Setup once. It is the built-in fallback for an incomplete automatic update. See First steps.
