Keen Software House Game Engine

VRAGE

VRAGE™ is a series of in-house game engines developed by Keen Software House. VRAGE stands for “volumetric rage” and/or “voxel rage”.

VRAGE’s core feature is volumetricity within the environment. Volumetric objects are structures composed from block-like modules interlocked in a grid.

Volumetric objects behave like real physical objects with mass, inertia and velocity. Individual modules have real volume and storage capacity and can be assembled, disassembled, deformed and destroyed.

VRAGE3

VRAGE3 is our new, next-generation game engine powering Space Engineers 2. It has been designed specifically to handle complex, dynamic worlds and advanced physics interactions. With VRAGE3, we’re able to offer significantly improved performance, richer visuals, and enhanced modding capabilities.

One of the key strengths of VRAGE3 is its flexibility and scalability, allowing creation of vast and detailed environments. From realistic physics and water simulation, to refined grid systems and better destruction mechanics, VRAGE3 delivers an immersive sandbox experience unlike anything we’ve created before.

We are always looking for new colleagues who seek technical and artistic excellence and who like to push their limits.

VRAGE2

The VRAGE2 engine is designed to support extremely large and fully dynamic and destructible environments, including planets with up to 120 km in diameter and a surface area of 45 238 km2, large space ships and any other creations built by the players. VRAGE empowers our community to build everything they want in space and on planets!

Due to Medieval Engineers development, VRAGE received a fresh upgrade: structural integrity and DirectX 11 rendering. With the addition of planets to Space Engineers, the engine went through a major upgrade to support large scale volumetric entities.
