Build absurd physics-driven siege machines and flatten medieval fortresses. Besiege rewards engineering creativity over pre-set solutions.

Besiege is a physics sandbox where your job is to design, build, and unleash medieval siege engines on a series of increasingly stubborn fortresses, towns, and objectives. It sits somewhere between a puzzle game and a pure sandbox: each level hands you a goal (destroy the castle, kill the soldiers, collect the flag) and then gets out of the way while you figure out how to construct something capable of doing it. That something can be a lumbering catapult, a spinning blade platform, or a jet-propelled death wheel that technically violates the spirit of the medieval theme. Spiderling Studios never punishes creativity, which is the game's biggest strength. From a systems perspective, Besiege is deceptively deep. Every block has physical properties: weight, drag, structural integrity. Add too many spinning blades on one side and your machine torques itself into the dirt before it reaches the enemy gate. Get the counterweight wrong on a trebuchet arm and your projectile lands behind you. The building interface is clean enough that you can get a functional catapult running in about fifteen minutes, but optimising a machine to clear a level without losing a single sheep (yes, that is a real constraint in some stages) pulls you into genuine mechanical problem-solving. The progression curve respects newcomers without babying them, which matters. The sandbox mode and Steam Workshop are where the real long-term value lives. The community has built functional helicopters, automobiles, calculators (yes, calculators), and enormous multi-stage war machines. If you have any interest in the mod ecosystem, Besiege is one of the better examples of a sandbox that improves dramatically with community content. Multiplayer was added post-launch, letting you build alongside or against other players, which turns the already chaotic physics into something genuinely unpredictable. AI opponents are not really a factor here since the game is primarily about construction rather than strategic opposition, so do not come in expecting tactical depth on the enemy side. Where Besiege loses points is in its campaign length if you are not a sandbox type. The base set of levels is finite, and players who want a clear finish line with escalating narrative stakes will find it thin. The game also does not hold your hand through advanced building techniques - things like using hinges for folding mechanisms or chaining logic blocks for timed sequences require either experimentation or a trip to a community guide. That gap between basic builds and impressive ones is real, and bridging it takes patience. For the spreadsheet-minded among you: expect around 10-20 hours to clear campaign levels and effectively unlimited hours if the sandbox hooks you. For my money, Besiege earns its overwhelmingly positive rating honestly. It does one thing - physics-based machine building - and executes it with enough mechanical fidelity to stay interesting well past the tutorial. The Workshop keeps content fresh, multiplayer adds chaos, and the freedom to solve problems however your engineering instincts (or disasters) lead you is genuinely satisfying. If you want strategic AI, tech trees, or a grand campaign, look elsewhere. If you want to spend an afternoon making a spinning cannon tower that somehow works, this is exactly that.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
