Red Faction for PC was pretty damn sweet. I love how it had the ability to tunnel through walls and blow everything up. If you didn't have a key to a wall, you may be able to blow around it if you had enough rockets happy: But then they sometimes reinforced the walls with some sort of impenatrable wire.
