10 Video Games That Blew Your Mind (Without You Realising)

10. Red Faction: Guerrilla

Making a game where you can destroy everything in sight sounds simple enough. Just have all the structures in the game be made out of balsa wood, Styrofoam, and the hopes and dreams of DC fans. But accounting for how the physics engine will react to that destruction is a complicated process, which is why most games just don't bother.

Red Faction has always boasted destructible environments, even if the first two games failed to really implement them effectively. But Guerrilla, the long-awaited sequel by Saints Row developer Volition, took the idea and ran with it, making the GTA game that we all really wanted: one where you can lay waste to literally everything around you.

This was done by upgrading the revolutionary Geo-Mod engine used in the original games into the Geo-Mod 2.0 engine. This engine provided a "stress-based" collapse model for buildings. Ensuring that every building would have weight and mass to it, so that the player has to put in that extra bit of work to get a building to come down.
