Besiege The Broken Beyond

Besiege: The Broken Beyond is an expansion that lets you build and pilot spacecraft across a star system using orbital mechanics. It adds an 11-level interplanetary campaign, 13 space-themed building blocks, a fuel system and a space environment for multiplayer battles.

Campaign in the Aranea system

The campaign begins with a launch from Ipsilon into the Aranea system, which is occupied by the space-faring Void Drifters. You battle swarms of alien spacecraft, race them through Doon’s desert canyons, lay siege to a fortress built into a floating asteroid and send a moon crashing out of orbit to destroy the planet below.

Build and fuel machines

The 13 new space-themed blocks let you create machines for the new environment. A dynamic fuel system adds resource management: rocket boosters, flamethrowers and blasters consume fuel. You balance fuel storage against your machine’s mass so it has enough to fly and use its weapons without becoming too heavy to lift off.

Gravity and atmospheres

Large objects in the levels generate simulated gravitational fields. You can jump between asteroids or establish orbital paths around multiple celestial objects. Different kinds of gravity create planets you can land on and planetary discs you can drive around or fall from toward the planet below.

Space debris includes rocks to collide with or move, meteoroids to push around or smash together, and moons that you can send out of orbit. Planets also have atmospheres that simulate aerodynamic effects: propellers can provide propulsion, wings and balloons can generate lift, and drag can slow atmospheric entry to help prevent a machine from burning up if it enters too quickly or at a bad angle.

Sandbox and multiplayer

Outside the campaign, an interplanetary sandbox contains planets, moons and structures to explore and destroy. The expansion also adds a space environment for multiplayer battles and new objects to the level editor, where you can place planets and customize gravity.
