Let's not forget the slightly revised VRW arena:

The Weapon Shop:

The arena is essentially a 20m x 20m platform with pipes above the arena. The walls are 50cm high, and there are 3 of them. The last wall is a polycarbonate panel that retracts downward when a release button is pressed, and exposes the robot to 3 side-by-side conveyor belts with small barbs on them to grab robots. These belts lead to a 3m x 4m pit, and will pull your robot into it. Don't worry about your robot though, as the 6ft deep pit is filled with a section of soft Tempur-Pedic mattress foam, so your robot won't get badly damaged. In each of the 4 corners, there is a propane flamethrower exuding flaming gas at a temperature of 500 degrees Fahrenheit. On the 2 walls opposite eachother, there are 2 140cm wide drums, each powered by a custom built 135hp engine mounted outside the arena. Each drum spins at a dangerous 5000rpm, and puts out over 300kjs! The wall opposite the panel contains 2 CPZs: One on the left side of the wall, and one on the right side. Each of the CPZs is a 4m x 5m rectangle, and contains 1 house robot. in between the 2 CPZs, the is a 10m gap, and on the wall is the button to release the polycarbonate panel and expose the conveyor belts. We're not done, however. There are 6 50cm diameter special alloy pipes running above the arena. These pipes are filled with burning thermite, and purposely leak a bit, so if some drips on your robot, watch out! There's a grill in the middle of the arena that spews out Co2, so if some thermite drips on you, head to the the grill to cool yourself off.

Anyways, start sending in your tactics & predictions now.
