Besiege is a physics building game about constructing medieval machines to annihilate armies, obliterate castles and overcome challenging obstacles. Conquer the campaign or skirmish with friends in Multiplayer!
Developed by Spiderling Studios · Published by Spiderling Studios









You build machines to complete objectives across a medieval campaign of destructible levels spanning four island nations. Challenges include attacking armies and fortifications as well as solving puzzles and navigating obstacles.
A construction system lets you connect blocks and mechanisms into siege engines and other vehicles. Physics shapes how each design moves and holds together, so you can test a machine, see what happens, and revise it to better suit the task.
Sandbox levels offer space to experiment beyond campaign objectives. You can also play multiplayer, use the level editor to create custom challenges, and explore community-made machines, levels, and mods.
In this helpfulness-selected sample, players often enjoy the freedom to invent machines and the cycle of testing, breaking, and improving them. Reviewers also praise the physics and the entertaining destruction, and some enjoy finding different solutions to campaign challenges. Criticism includes a steep learning curve and sparse guidance; some players also find later campaign levels repetitive or mention camera and performance problems.
