Minecraft Battle Mode for Xbox One

According to the Minecraft Wiki page, Battle Mode is a mini-game for the Legacy Console Editions of Minecraft that is very similar to the popular server game Hunger Games. It was introduced in the Xbox 360 TU36, Xbox One CU25, PlayStation
1.28, Wii U Patch 7, and Nintendo Switch Patch s1 updates.

So basically, you need Minecraft Xbox One edition, which is no longer available from the store, but you might still be able to find a disk version of the game from your local or online game retailer.

If you mean the Server-Mode Hunger Games, you will need to play JAVA Minecraft on a PC and connect to specific Minecraft Servers running the Hunger Games mods.

On the Xbox console, you can only connect to featured servers, and can't join those fancy PC servers running Hunger Games.

You can either prepare a Hunger Games map yourself, and then invite a few friends to your map on the console but are limited to a hand full of players from your friend list, or you can do the next best thing, and join a Battle Royale mode on one of the featured
servers.

For example the Lifeboat Server features a Battle Royale mode (https://lbsg.net/how-to-play/battle-royale/)

Or Survival Mode on Mineplex: https://www.mineplex.com/games/bedrock-survivalgames/

Cubecraft also features Survival Games https://www.cubecraft.net/leaderboards/view_leaderboard.php?network=bedrock&game=survival_games

I have unlocked all the characters, coop mode and battle mode. But when I open either coop mode or battle mode, it says xbox live restriction for it. My xbox live is open but it is saying like that. Can anyone please help me on this!!

The Battle Royal mode is free to play. If you paid for the game it was for the single player portion. To play the battle royal you need Xbox live good to play online.

Definitely Battle Royal Mode 😍
