Gameplay

In Besiege, your main goal is to create destructive machines—think artillery, stone cranes, and more—to eliminate the mission target. Early levels use relatively basic materials, mostly wood and small steel parts, so don’t expect everything to look or behave like a modern arsenal right away.

What really defines Besiege is the realistic physics. If your weapon or machine is too heavy, or if it gets hit by recoil during an attack, it may be damaged immediately. Because of that, you’ll often need to optimize your design—sometimes even what you want to build just won’t work in practice. Still, Besiege gives you plenty of freedom to try your ideas and make them work.

Features

Intuitive building system

Build your creations with an assembly system featuring 70+ parts you can mix and match to tackle the destruction challenges.

Unleash your imagination

Create complex machines—like a giant tank built from multiple components—where different parts can serve different functions.

Conquer destructible levels

• 55 levels to explore, each giving you room to experiment and destroy buildings in your own way.

Benefits

Craft giant fighting machines

Early on, Besiege typically asks you to destroy simpler targets, such as huts and wooden carts. As you progress, the missions get tougher—targets may include solid rocks and large structures. Against heavy obstacles, your creations can fail quickly, breaking apart or exploding into many pieces if they can’t handle the job.

Because of this, upgrading and crafting matter a lot. They can be the difference between winning and losing.

Conquer the levels

To challenge your build skills, Besiege includes 55 different levels. Each stage introduces a new target that grows more powerful and harder to break. You’ll also fight across different environments, including islands, deserts, and rocky mountains. New military-style constructions can appear there, so you’ll need to adapt your methods rather than relying on one “always works” design.

Plan carefully: observe the target, figure out what needs destroying, then assemble your machine. Building can take a long time—sometimes you may spend an entire day constructing a massive vehicle. Once your weapon frame is ready, you can attach cannons and accessories to reinforce key parts of your build.

Craft giant weapons

Different weapon types need different components and details. To use them, you must unlock the required parts. You can earn unlocks by completing missions and clearing many levels. Your achievements throughout the game help you gain access to more parts.

For example, you can build planes using Flying blocks together with steering hinges to connect and control sections of the aircraft. After unlocking parts, you can reuse them repeatedly without worrying about running out.

With the parts you unlock, you can also create many other machines such as tanks, helicopters, sports cars, catapults, missiles, and more—limited mostly by your creativity.

Add weapons

Once you’ve built a machine or combat vehicle, you can boost its damage by attaching powerful weapons directly to the body. Tanks can be equipped with more destructive cannons, while planes can carry bombs. With the right loadout, attacks can become faster and more effective against targets.

Don’t forget protection and upgrades too—attach accessories like spikes or large drills to help your vehicle survive and perform better. Download Besiege and build destructive machines to take on castles, armies, and obstacles.
