When it comes to proving that its in-game destruction system is the best in the industry, Red Faction: Guerrilla developer Volition isn't messing about.
"This is Mercenaries 2: World in Flames," Volition's Dan Cermak announces across the packed London hotel room, as a video clip appears on screen with a rocket hitting and destroying a large monument.
"What they're doing is taking a model and replacing it with a dead one," the Red Faction man notes. "The building actually drops through the world and another model appears in its place. It works very well and it's a good way to show destruction, but it is basically a slight of hand."
