GrE writes, "I remember playing the original Red Faction on PlayStation 2 way back in 2001. The greatest achievement was the Geo-Mod engine, allowing players to destroy environments. When I approached a door that I couldn't get past, I simply blew up the frame surrounding the door and watched the physics take over.
In Red Faction: Guerrilla, the Geo-Mod engine has reached 2.0 and it shows. 99.7% of the objects in the world of Mars are destructible. Everything from the vehicles, buildings, and even people can all be destroyed or demolished. Only very specific objects cannot be destroyed, and the explanation of why actually makes perfect sense. If the game was Adults Only, I'm sure there would be body parts flying everywhere."
