The Blue ID Tag is an admin-only item that can be exclusively acquired on non-event servers via spawning from the F1 console. It is a primary resource used during the Rust Twitch Rivals exclusive streamer event as a token for calculating the winning team of the event.
During the event, players may only acquire this tag by looting the player corpse of a member of the Blue team. Players may also loot their own corpses or those of their fellow teammates to prevent the enemy team from getting credit for this token.
This item serves no other purpose and is subject to removal from the game after the event.
