- Enter codes into the box.
- Hit the button marked ‘Redeem’.
- If the code was right, you should get a pop-up showing what items you got.
- Go to the MMV page on Roblox. We’ve linked to it above.
- Hit the ‘Servers’ option under the play button.
- Select ‘Create Private Server’, a button just under the ‘Servers’ tab title. If nothing has changed, this should be free and cost you 0 Robux.
- Once you’ve created your server, find it on the server tab and join it.
- You should jump into the MMV lobby.
- As you’re the only player, you shouldn’t need to jump into any matches, so you can put codes in at your leisure.
- Anything you redeem on the private server should be carried over to the public ones.
