Optimus Prime Armor!

Quickstart

1. Craft all four Prime Commander armor pieces (see recipes below) and equip them in all four armor slots.
2. Step into third-person view — your player model is replaced by a large, fully animated Optimus Prime–inspired mech. The camera automatically backs up so the mech fits on screen without clipping.
3. To transform into Truck Mode, Sneak + Look Down while wearing the full set. A transformation sound plays and you become a driveable semi-truck.
4. While in Truck Mode, Left-click to rev the engine, trigger rumbles, and play air-brake hisses.
5. Carry a Prime Commander Trailer in your inventory while in Truck Mode, then right-click it to open a 54-slot cargo chest.
6. To return to mech form, exit Truck Mode (remove Sneak+LookDown trigger or remove a piece and re-equip).

Overview

Optimus Prime Armor! is a cosmetic and gameplay armor mod that transforms your character into a large Optimus Prime–inspired mech when the full four-piece Prime Commander set is worn. It includes a Truck Mode transformation, a throwable Energon Battle Axe, a cargo Trailer, and a suite of powerful full-set status effects.

What It Adds

How To Use

Mech Mode (Full Set Worn, Not in Truck Mode)

• Equip all four armor pieces to activate the oversized mech renderer.
• The camera automatically shifts to a backed-up third-person view so the mech is fully visible without screen overlap.
• Animations (stride, arms, hips, knees, forward-lean) run smoothly at a slightly reduced scale.
• Removing any piece instantly returns your normal player model and camera.
• In first-person view, the empty hand is hidden for immersion.

Truck Mode

• Trigger: Sneak + Look Down while wearing the full set.
• Your character transforms into a semi-truck with full sound effects (engine start, diesel idle, air brakes, road rumble).
• Left-click while in Truck Mode to manually trigger engine noise, revs, and hisses.
• Speed is enhanced while driving.
• Ram Attack: Moving fast in Truck Mode automatically damages and knocks back nearby entities.
• To exit Truck Mode, perform the same Sneak + Look Down input again.

Energon Battle Axe

The axe is a special weapon that exists only while you wear the full set outside of Truck Mode — it cannot be dropped or kept otherwise.

• The axe deals 25 damage per hit.
• Flame and electric spark particles trail the axe in flight.
• A cooldown applies to the special attack (~11 seconds).

Prime Commander Trailer

• Craft the Prime Commander Trailer and keep it anywhere in your inventory.
• Transform into Truck Mode first.
• Right-click the Trailer item to open a 54-slot "Prime Commander Trailer Cargo" chest.
• The inventory persists on the item between sessions.
• The Trailer cannot be placed inside itself.

Crafting And Obtaining

All recipes are unlocked automatically when you join a world.

Prime Commander Helmet

The Energon Battle Axe is not craftable — it appears automatically in your hand when the full armor set is equipped outside of Truck Mode, and disappears when conditions are no longer met.

Abilities And Mechanics

Full Set Bonuses (all four pieces required)

Mech Renderer & Camera

• Wearing all four pieces replaces your third-person model with the animated mech.
• Camera automatically switches to a backed-up third-person rear view to prevent the large model from overlapping the screen.
• The mech uses a slightly reduced render scale and smooth, calmer animations.
• Removing any single piece immediately reverts to the normal player model and camera.

Progression And Strategy

• Early goal: Gather Netherite Ingots, Diamond Blocks, Redstone Blocks, Iron Blocks, and an End Crystal to craft the full set. These are late-game materials, so the armor represents a strong endgame power fantasy.
• Truck Mode combat: Use the Ram Attack by moving at speed toward enemy clusters in Truck Mode for AoE burst damage and knockback.
• Axe play: In mech form, use the boomerang throw to hit enemies at range, then follow up with the Storm Axe special to chain-target multiple enemies. Mind the ~11 second special cooldown.
• Trailer utility: Keep a Trailer in your inventory at all times for 54 extra slots of storage — accessible any time you transform into the truck.
• Camera tip: If the mech ever feels too large in third-person, remember the camera backs up automatically. You can scroll your FOV or zoom out further with your mouse wheel if needed.
