Besiege Tips - Build Stable Machines Before Clever Ones

Content note: Besiege can include frequent machine violence and gore. This guide stays focused on construction, physics, testing, and clean beginner habits.

Besiege is a physics-building sandbox by Spiderling Studios about making medieval machines that survive long enough to do a job. A good machine is not the one with the most parts. It is the one whose frame, power, steering, and center of mass all agree with the task.

This guide covers base Besiege fundamentals across current PC and console-style play. PC has the broadest ecosystem for Workshop, Multiverse, editor, and mod features, while console editions use a reworked controller-focused interface and may differ in feature parity. The Splintered Sea expansion adds water, ocean levels, a separate sandbox, and aquatic blocks; those mechanics are outside this base-game guide unless clearly labeled.

Essential Tips

1. Start With the Objective, Not the Machine

A catapult, cart, flyer, and ram all fail for different reasons.

Before placing decorative or weapon blocks, decide what the machine must do first: move forward, turn, lift, push, carry, survive an impact, or hit a target. Build the smallest working frame for that job, then add complexity only after it moves predictably.

2. Make the Frame Strong Before Adding Power

More force makes weak construction fail faster.

If a machine twists when it starts, the problem is usually structure before speed. Reinforce long spans, connect load-bearing sections from more than one direction, and use braces where a frame needs to resist bending. Braces are especially useful because they add stiff support without turning every build into a bulky box.

3. Treat Joints as Flexible, Not Magical

A hinge, swivel, or steering part still lives inside the physics system.

Joints can flex, stretch, vibrate, or snap when a heavy section pushes through them. Keep powered and unpowered joints close to the loads they control, avoid long thin lever arms when you need strength, and test whether a joint bends under normal movement before attaching weapons or extra weight.

4. Watch the Center of Mass

Besiege machines rotate around their weight, not around your intention.

If a vehicle tips, noses down, spins strangely, or refuses to steer, look at where its mass is concentrated. Heavy parts mounted high or far to one side can turn a simple drive test into a rollover. Add weight deliberately, keep essential mass low when possible, and test balance before finalizing controls.

5. Choose Steering for the Surface

The right steering method depends on friction and size.

Articulated wheel steering is a natural first choice for ground vehicles. Skid steering can turn tightly, but it strains big or heavy machines. Torque steering is better for low-friction craft, aircraft, or unusual builds. Thrust and aerodynamic steering need careful placement and enough movement speed to matter.

6. Balance Power Against Control

A machine that launches itself apart is not underpowered.

When propulsion, spinning parts, pistons, or weapons overwhelm the frame, reduce the job to one motion at a time. Test driving before attacking. Test lifting before carrying. Test firing before moving. A slower stable machine often beats a faster one that breaks before the objective.

7. Use the Camera Like a Tool

Many building mistakes hide behind the first angle.

Rotate around the frame, change your viewing target, and inspect joints from the side before simulating. Check whether wheels point the same way, braces attach where you think they do, and powered parts have room to move. A clean camera pass saves several broken test runs.

8. Test in Small Loops

Do not wait until the final machine to learn what fails.

Run short tests after each major change: frame, wheels, steering, power, weapon, armor, then objective attempt. If a new part causes failure, remove or adjust only that part first. Besiege rewards iteration, not one huge build session followed by guesswork.

9. Slow Down Messy Failures

A quick explosion often hides the real first break.

When a machine tears itself apart, use slower simulation to see which connection, joint, or load path fails first. Then retest at normal speed before trusting the fix. Slow testing is a diagnostic habit, not a replacement for full-speed reliability.

10. Keep Sandbox Habits Separate From Level Solving

The sandbox is where you learn physics without objective pressure.

Use sandbox areas to test steering, balance, power, and structural ideas before adapting them to campaign levels. Save exact level solving for a separate attempt. A clean prototype teaches more than a half-built machine wedged into a mission space.

Build From the Job Backward

The simplest Besiege planning question is: what motion must happen first? If the machine must push, build a low front frame and test contact. If it must carry, build the platform and balance it before adding weapons. If it must fly or hover, test lift and steering without a payload. If it must turn while moving, prove steering before adding force.

Think in load paths. A powered wheel pushes into an axle, the axle pushes into a frame, and the frame pushes into the rest of the machine. If that path is a single weak joint or a long unbraced pole, the whole build inherits the weakness. Add braces across triangles, shorten bendy sections, and avoid placing heavy or violent parts at the end of unbraced arms.

Power should arrive last. Once the frame survives basic movement, increase force gradually. If the machine starts wobbling, do not hide the wobble with more wheels or more thrust. Find the part that flexes first, then reinforce or simplify.

Stability and Steering Checklist

Question	What to Look For
Is the frame symmetrical enough?	Uneven weight or uneven wheel placement can pull the build sideways
Are long spans braced?	Unbraced beams twist when power or impact reaches them
Is mass low and centered?	High or side-heavy parts make rolling and tipping more likely
Do joints carry too much load?	A joint that bends during a basic test will fail under weapons or impact
Is steering matched to the build?	Heavy machines need steadier steering than light experimental craft
Does each powered part have clearance?	Moving parts that hit the frame can destroy the machine from inside
Can you see the failure clearly?	Camera angles and slow tests help reveal the first weak point
Did the machine work at normal speed?	A fix is only trustworthy after a normal-speed retest

For ground builds, begin with stable wheel placement and modest turning. For flying or low-friction machines, expect balance and thrust placement to matter more than wheel logic. For heavy machines, assume every turn, collision, and weapon recoil will test the frame.

Testing Routine

1. Frame test - Simulate the empty structure and look for sagging, twisting, or wobbling.
2. Movement test - Add locomotion and drive without weapons or payloads.
3. Steering test - Turn both directions and watch whether the frame fights itself.
4. Power test - Increase force gradually and check for vibration or snapping.
5. Load test - Add the payload, weapon, armor, or front ram and repeat movement.
6. Impact test - Hit the kind of obstacle the machine is meant to handle.
7. Slow failure test - If it breaks instantly, slow the simulation and identify the first failure.
8. Normal-speed retest - Confirm the machine still works when the physics run normally.
9. Objective test - Only then bring the prototype into the level or challenge.

Common Mistakes to Avoid

1. Do not add power to a bending frame - Reinforce the weak section before increasing speed, lift, or weapon force.

2. Do not ignore side-to-side balance - A machine that looks stable from the front can still roll because heavy parts sit off-center.

3. Do not rely on one joint for a heavy moving section - Support the load so the joint controls motion instead of carrying the whole machine.

4. Do not steer every build the same way - Wheels, skid turns, torque, thrust, and control surfaces suit different surfaces and weights.

5. Do not test only at slow speed - Slow motion helps diagnose failure, but normal-speed testing proves whether the build is dependable.

6. Do not hide collisions inside the machine - If moving parts hit your own frame, the machine may destroy itself before enemies touch it.

7. Do not copy expansion habits into the base game - Water, buoyancy, and aquatic blocks belong to Splintered Sea-specific building.

8. Do not let Workshop machines replace practice - Downloaded builds can inspire ideas, but your own tests teach why a design works.
