  1. Run the setup. Download Syphon Vault, open SyphonVault_WebSetup.exe and click Install. It gets the newest Syphon Vault and installs it for your Windows user, so no admin rights are needed. The setup is signed by Kaltora Arise B.V., Syphon's publisher. If Windows still warns you, click More info, then Run anyway. If Windows says Smart App Control blocked it, read why.
  2. Install RevivalRO Loki. In Syphon Vault, press Install on RevivalRO Loki and pick a folder, or keep the default C:\Games\Revival. It downloads the game, checks every file and puts it in place. You can pause the download and carry on later.
  3. Press Play and log in. When Windows asks to allow the patcher, click Yes: it looks for game updates first, then the game opens. Log in with your game account (no account yet? register for free), create your first character and use @go 0 to teleport to Prontera.

Download FAQ

Quick answers to the most common install questions.

Is Syphon Vault free? Do I need another account?
Syphon Vault is free to download and to use, and it works without a Syphon account. To play you only need your RevivalRO Loki game account from this website. A free Syphon account is only needed for extras such as the chat and Syphon Tools.
Do I need admin rights?
Not for Syphon Vault: it installs for your Windows user, and its own updates never ask for permission. Windows does ask when the game needs something from Windows, such as DirectX, and when you press Play, because the RevivalRO patcher asks for administrator rights.
I already have RevivalRO Loki installed. Do I have to download it again?
No. Syphon Vault finds a copy that the older RevivalRO setup installed and offers to take it over, so it can update and repair it from then on. Is the game in another folder? Use Locate an installed game in My Library.
The download is slow or stalls. What can I do?
Syphon Vault downloads the game with resume: pause it and carry on later, and a lost connection or a restart of your PC does not start it over. It keeps downloading while it waits in the tray. If it keeps stalling, try a different network, or ask in Discord for help.
Do I need to download anything else after installing?
No. Syphon Vault also installs what the game needs from Windows, such as DirectX 9 when it is missing. When you press Play, the patcher downloads the latest patches first: let it finish before clicking Start. A new version of the game files comes through Syphon Vault, which downloads only the files that changed.
Windows or my antivirus warns me. Is it safe?
Syphon Vault and its setup are signed by Kaltora Arise B.V., Syphon's publisher, with a certificate Windows trusts, and every game file is checked against a list signed by Syphon before it is installed. If Windows still warns you about a new version, click More info, then Run anyway. Private server clients often trigger antivirus false positives; if yours blocks the game, add the game folder (C:\Games\Revival by default) to its exclusions.
The game crashes or shows errors on startup?
Open RevivalRO Loki in Syphon Vault and use Repair: it checks every file and puts back what is missing or damaged, and your saved settings stay. If that does not help, install the Visual C++ Redistributable 2015 or newer, update DirectX, or try compatibility mode (Windows 7). On Android, make sure you have enough free storage. Still stuck? Ask in #tech-support on Discord.
Can I use the same account on PC and Android?
Yes. Your account, characters, and items are shared between PC and Android. Play on PC at home and continue on your phone. Both connect to the same Loki server.
What are the server connection details?
None needed: the client is pre-configured to connect to Loki, and the patcher handles server addresses automatically. For proxy connections (SEA/EU/SA), choose one in-game with the proxy selector.
How do I remove Syphon Vault?
In Windows, open Settings, then Apps, and uninstall Syphon Vault there. Your games and your settings stay, and the game's shortcuts start it directly again.
Free to play since 2004
