Description:
The Tunnel Runner is a large, self-propelled tunneling vehicle that seats two players and handles every phase of underground work in one machine. It drills 3×3 tunnels, smelts your ore on the fly in a three-lane furnace, stores everything in a 54-slot cargo hold, lays rails behind itself automatically, and even defends against mobs with its active drill head. Everything is accessible from the saddle without dismounting.
| Feature | Details |
|---|---|
| Vehicle | Multi-block entity, roughly 5×2×5 blocks in footprint |
| Drill | Active front drill that mines 3×3 and damages/knocks back mobs |
| Cargo hold | 54-slot inventory built into the vehicle |
| Three-lane smelter | Smelt ore in three parallel furnace lanes while you drive |
| Rear rail layer | Automatically places rails on the tunnel floor behind you |
| Utility bay | Holds track/support materials; can place blocks while mining |
| HUD | Speed, heading, fuel bar, heat bar, and drill-mode indicators |
| Seating | Accommodates a pilot and one passenger; either can steer and use menus |
| Sound | Engine hum and wheel rumble with speed-based pitch |
Right-click anywhere on the vehicle to mount. The game automatically switches you to third-person view so you can see the vehicle. When you dismount, your previous camera setting is restored.
| Key | Action |
|---|---|
| W / S | Move forward / backward |
| A / D | Steer left / right |
| Space | Drive mode: 4-block forward diagonal jump |
| Shift | Drive mode: 4-block forward diagonal dive |
| Ctrl | Exit / dismount |
| E | Open the Tunnel Runner menu |
The vehicle defaults to Drive Mode on mount. The on-screen HUD shows current speed (blocks/second), heading in degrees, fuel level, heat level, and the active mode.
Hold Left Mouse Button to activate the drill. The vehicle slows to mining speed and bores a 3×3 tunnel directly ahead. The HUD updates to show the current drill grade.
| Mining input | Behavior |
|---|---|
| Hold LMB | Level 3×3 cut |
| Hold LMB + Space | Shallow upward cut (3 forward / 1 up) |
| Hold LMB + Shift | Shallow downward cut (3 forward / 1 down) |
| Hold LMB + Space (no W) | True 45° upward diagonal |
| Hold LMB + Shift (no W) | True 45° downward diagonal |
Broken blocks are automatically collected into the cargo hold. The drill also damages and knocks back any mobs caught in front of the vehicle.
Hold Right Mouse Button while moving forward to place items from the utility bay. Placement works anywhere, including outside tunnels, and can run at the same time as mining. Manual placement matches the slower mining speed for precision.
Auto Place mode: when the vehicle detects an open 3×3 space ahead, it automatically places supports and the current grid layer from the utility bay without any button held.
Pressing E while riding opens a multi-tabbed menu that includes:
You can also Shift-click the rear of the vehicle model to open the rear utility bay directly.
Craft the Tunnel Runner at a crafting table. The recipe is unlocked as soon as you join a world.
The recipe combines two diamond pickaxes, a redstone lamp, two iron blocks, a chest, two minecarts, and a furnace — reflecting every system packed into the machine.
As the Tunnel Runner moves, a rail-laying module under the rear deck places rails from the utility bay onto the floor behind it. Keep rail items stocked in the utility bay (use the +buttons to refill) and the vehicle will always leave a rideable track in its wake.
The onboard furnace runs three independent smelting lanes simultaneously. Load fuel once and feed raw ore into any of the three input slots. Finished ingots go to cargo. The smelter runs continuously while you drive.
The spinning drill head at the front damages and applies knockback to any mob that walks into it. Hostile mobs in a tunnel ahead of you will be pushed back or killed as you advance.
Riders cannot take suffocation damage while inside the vehicle, even when the drill head is actively cutting through solid rock.
Because Shift is used for the forward dive maneuver, it does not dismount you. Use Ctrl to exit the vehicle.
Record your sessions and play them back with actors that preserve each player’s exact skin, model, overlays and natural movement — just record as usual and open your replay from the in-game browser to watch, scrub and export sessions. The system is built for stability and scale: it concentrates recording on nearby entities, snapshots terrain gradually, deduplicates repeated block-state changes, ignores synthetic neighbor updates, enforces memory and per-tick limits, and flushes saves asynchronously so big fights, farms and long timelines replay reliably; visual fidelity during playback is improved for held and ranged items and item ghosts are rendered safely with restored shader state. If the Epic Fight mod is present, an optional lightweight compatibility bridge records and replays first-stage combat states (battle mode on/off, combat locomotion and idle/walk/run flags, combat pose, weapon category and transition state) and routes replay actors through Epic Fight’s renderer when available, otherwise it falls back to a stable basic holding pose; advanced Epic Fight skills, combos and special abilities are intentionally not recorded, and debug logs report detection and sync status.
Equip the full Prime Commander armor set to replace your third-person player model with a large, fully animated Optimus-style mech; when the full set is worn and you are not in truck mode the mech renderer takes over and the camera automatically switches to a backed-up third-person back view while first-person still hides the empty hand for immersion. The robot features the new reference-matching blue helmet, black visor with cyan eyes, silver faceplate and crest, intact transformation and movement animations, and updated armor/item icons to match the red, blue and silver look; remove any piece or switch to truck mode to return to the normal player render, and truck mode now reliably spawns only one truck shell per player. Truck-mode ramming now knocks targets back harder with a slight lift and plays a new truck crash sound on impact (with a short cooldown to prevent audio spam), and the truck’s engine start, drive, idle and rev noises have been revamped to a raw, high-power diesel sound layered with the existing road hiss for a more visceral vehicle experience.
The Tempest Cloud Cruiser is a rideable multiblock flying cloud vehicle you build and activate by right-clicking any part to transform it into a hovering cruiser; while piloting use WASD to move, Space to ascend, Shift to descend, your view to turn, and Ctrl to exit (which returns the item to you). While flying, press [ (left bracket) to cycle the weather/disaster menu through Clear Sky, Rainstorm, Thunderstorm, Lightning Strike, Earthquake, Fire Storm, and Chasm, then right-click to trigger the selected effect; a HUD displays your speed, altitude, heading and current mode and automatically switches to third-person so you can see the full cruiser. Earthquake shakes and launches nearby entities while damaging them and cracking surface blocks with explosion and anvil sounds; Fire Storm rains burning embers across a large area, setting fires and igniting nearby entities; Chasm tears open a deep directional trench in front of you to rip through the ground, and status messages report how many fires or blocks were affected; the Tornado Gust option has been removed.
The Skyhawk Gunship is a rideable military helicopter that you can place as a multiblock structure and then mount by right-clicking any part of it. Once inside, you fly using WASD to move horizontally, Space to ascend, and Shift to descend, with the helicopter facing the direction you look. Press Ctrl to dismount and leave the helicopter parked in the world, ready to be boarded again later. While piloting, left-click to fire rapid machine gun bursts and right-click to launch explosive missiles at your targets. A full cockpit HUD displays your speed, altitude, heading, and weapon status to keep you informed mid-flight.
The Sky Baron Biplane is a decorative multiblock structure that brings a fully animated, sound-producing biplane to life in your world. Once the structure is assembled and placed, you can right-click any part of it to toggle the engine on or off -- no need to hunt for a specific block. When the engine is running, it roars to life with a looping engine sound, billowing smoke and cloud particles from the propeller and exhaust, giving the biplane an authentic, immersive feel.
