Servo reminds me of 'Metal Fatigue', and its about time!

It's unlikely many of you have played Metal Fatigue, but there were 3 basic teams. Each could build basic tanks, repair vehicles, aircraft, etc, but the main part of the game was giant battle robots.
You built the robots in 5 parts: A torso, legs, left arm, right arm, and a pilot.
The fun part was customising bots to specific uses. A Ninja robot with fast legs, stealth torso, and laser sword arms. A heavy robot with shield torso, heavy legs, a shield arm, and an axe arm. You get the idea.
The reason I bring this up, other than nostalgia, is that the part I found awesome, was that robots could literally hack each other to pieces. This left arms and legs (but never torsos?) all over he battlefield. This was important, because while each of the three sides had unique parts, you could use little utility vehicles to go and collect the bits and pieces laying about, and bring them back to your base for research and production. I would LOVE to see something like this in servo!
