Awesome / Red Faction

• Literally every time a building collapses in Guerrilla and you get to see the awe inspiring destruction physics is pure bliss. There's nothing like frantically running through a building while tanks blast at you from all sides and the walls get blown out in random directions.
• Incur a high enough wanted level in Guerrilla, and the EDF will send tanks after you. In later areas, some will have giant missile launcher arrays attached to the top. If you hijack it and use the secondary fire, the tank will fire off a rapid fire barrage of missiles that home in on whatever you're pointing at. It can decimate all but the most invincible structures in seconds.
• In Guerrilla, getting your hands on construction mechs, especially heavy ones. You can quite literally just walk through bases, destroying everything in your way, and EDF will most likely lack any anti-armor weaponry to counter you until it's too late.
