Altar SMP is a private content creator SMP where players craft legendary weapons found on Altars. Altar SMP started in June 6th 2025, and has since generated over 10m+ views on YouTube. Altar SMP has "Arcs", where new legendary weapons get added to the server, adding more weapons as the server progresses. Altar SMP Season 2 started on April 28 2026, wiping the previous season's world & weapons, and releasing the first set of 5 legendary weapons for Season 2. Now that the old weapons are gone for good, the Altar SMP plugin is slowly being released for players to enjoy them on their own servers!
