Minecraft’s Mounts of Mayhem game drop launched on December 9, 2025, for both Java and Bedrock Edition. It added the spear, new underwater mounts, hostile mounted mobs, and new armor. The original “less than two weeks away” countdown is no longer current.

When did Mounts of Mayhem come out?

Mojang announced a December 9, 2025 release date for Mounts of Mayhem, then confirmed the game drop had arrived that day. The original countdown appeared in Windows Central’s November 27, 2025 headline; it described an upcoming release at the time, not a future date now. Mojang calls Mounts of Mayhem the fourth game drop of 2025, part of its approach of releasing more frequent updates during the year.

Mojang’s release-day announcement confirms the launch, while its November 26 release-date announcement set the date. The earlier September 27, 2025 reveal introduced it as that year’s fourth game drop.

What did the update add?

The spear

The spear is a tiered weapon with two attacks: jab and charge. Charge damage depends on the player’s speed, so sprinting, riding, or traveling with an elytra can build momentum for a stronger hit. The weapon can be crafted in wood, copper, iron, gold, diamond, and Netherite tiers.

Nautilus mounts and underwater travel

The nautilus and zombie nautilus are underwater mounts. Mojang says riding one provides underwater speed and prevents the player’s air bubbles from decreasing while mounted. Bedrock’s release notes clarify that the Breath of the Nautilus effect pauses oxygen consumption; it does not replenish oxygen.

Changes to existing mounts

The drop adds Netherite horse armor alongside its new mounts and hostile riders. Its release notes also cover other mount-related changes, so players looking for exact behavior should use the notes for their edition rather than assume every detail is identical between Java and Bedrock.
