MU ONLINE TOOLSThe launcher your server deserves
It updates the client by itself, shows your news and events, alerts your players live and wears your server's design. Nothing to install on your VPS: everything runs through your hosting and your WebEngine.
Open, update and play
What they see when they open your server's launcher.
Lightning-fast updates
It only downloads what changed. The PLAY button fills with energy showing the percentage, speed and time left, and the window border changes color by status: ready, downloading, error or maintenance.
Events with countdowns
Blood Castle, Devil Square, Castle Siege… with your WebEngine schedule, in each player's local time.
Your news
Pulled automatically from your WebEngine or WordPress, with the first one featured large.
Default username
The player types their username once and it's filled in on the game login. Never the password.
Repair and requirements
Repairs damaged files with one button and installs Visual C++ if missing (official Microsoft installers only).
You control everything with the Publisher
A tool for your PC: publish updates, change the design and talk to your players.
Set up in 5 steps
Client, FTP hosting, your website, your server and publish. The Publisher finds the folder, the WebEngine connector and the events by itself.
Your design
Background, logo, colors, news image, your buttons and social links in the sidebar, in the order you want.
Always up to date
When a new launcher version comes out, your Publisher lets you know and you install it with one button. Your players get it automatically.
Live announcements
“Castle Siege in 30 minutes”. You type it in the Publisher and every player with the launcher open sees it in under a minute.
Maintenance mode
Locks the PLAY button with a countdown while you update. You can still get in with Ctrl + click.
Video background
Pick an MP4 and the Publisher converts it for you: a 10-second silent loop. Or snow, rain and fireflies.
Your server, alive in the launcher
What makes your players open the launcher even when there's no update.
Server panel
Players now and over the last 24 h, the guild that owns Castle Siege and your server's top players, live from your WebEngine.
Follow my character
Just their name, no password: level, resets and whether they're in game. It notifies on level-up and resets.
Voting with a timer
Your voting sites in the sidebar. The launcher remembers when each player can vote again and lets them know.
Pre-download and patch notes
Publish the patch early: your players download it now and it switches on by itself on the day and time you choose. Then they see the patch notes.
Client protection
Before playing it checks Main.exe, its DLLs and the files you choose. If someone touched them, it repairs them by itself.
Stats in your Control Center
How many players open your launcher, how many are on the latest version and update errors, with the file that failed.
Players only get in through your launcher
BG Guard is our antihack with its own protection server. It's sold separately and goes inside the launcher: your players install nothing else.
Secure session when pressing PLAY
It checks for cheat programs and files and requests an encrypted session from the BG Guard server. With Gate mode, opening Main.exe by hand doesn't connect.
New loading screen
The launcher minimizes and BG Guard stays in the middle: the bar reaches 100 %, turns green and then the game opens.
One license, everything included
The BG Guard license (BGG-…) also unlocks the full BG Launcher. If you're already on the Pro plan, BG Guard works with your Pro license.
Hide Main.exe
Only the launcher is visible in the game folder. It doesn't rename the main, so it works with Louis, MSPRO and SSeMU.
Start free, go Pro whenever you want
BG Launcher PRO comes with the Pro plan, along with the Pro Tools and the install guides. If the plan ends, your launcher keeps working in FREE mode.

What people usually ask
Do I have to install anything on my VPS?
No. Updates go through your web hosting (FTP) and player data, news and events come from your WebEngine.
Which server files does it work with?
With any Mu Online client. Saved accounts (My accounts) need Louis files or the Settings.ini AutoLogin; everything else works with MSPRO, SSeMU and others.
What if my Pro plan ends?
Your launcher switches to FREE: your players keep updating and playing the same, only the Pro features go away.
What about BG Guard?
BG Guard is a separate product: antihack with its own server, Gate mode on your VPS and a live panel. It lives inside the launcher (one checkbox in the Publisher) and its license includes the full launcher. See BG Guard.
Does it work for several servers?
The Pro plan includes your domain and 2 subdomains (for example s6.yoursite.com and classic.yoursite.com). The FREE version has no limit.
BG Launcher PRO, Pro Tools and install guides. Try it free for 7 days with your account.
