The GeoMod 2.0 engine, created by Volition, uses realistic physics to simulate building destruction. Instead of relying on pre-determined collapse points, structures on Mars crumble based on actual structural stress. Destroying buildings feels like solving an engineering problem – you can remove supports, weaken welds, and realistically bring down entire facilities. Everything that impacts structures – vehicles, explosions, and even a sledgehammer – uses the same physics system, making the debris behave consistently. Published by THQ, the game is still considered a prime example of how to create believable, systemic destruction in open-world games.
