Goal: Keep destroying the convoy vehicles before they reach the goal
Score for Gold: 221425

Strategy #1:

The score is based on destruction points, but instead of being on a timer it stops when one of the convoy vehicles reaches the goal point. There are four spawn points for the convoy vehicles on the north side of the map, and they appear two at a time whenever you destroy the active ones. On the radar they are the larger triangles. They take circuitous routes to the goal and are slow and easy to destroy to start with, but that changes more and more the longer you keep it going. For the first few waves you have time to destroy one convoy vehicle, then run around destroying other things for points before killing the otherone as it approaches the goal. After that you have to concentrate on them or you won't get to them in time to stop them from reaching the goal. Don't forget you have the R-button speed boost available to you. A quick way to destroy a convoy vehicle is to pick it up, then throw it or use it as a club to bash other things. If it's too close to the goal point to destroy with your guns that can be your last recourse.

Strategy #2:

I ran into the glitch. I stood infront of 1 convoy, got blast by a tank/heli(from behind). The convoy just froze on me! With the convoyfrozen,they couldn't reach their yellow marker. No new convoys could come out since they were frozen in play by the glitch...leaving me able to destroy whatever else is out there which gives you the score points. So I just went around destroying non-convoy things. Finally I just destroyed the frozen convoy's and let the next wave go by, since I was bored. It's really hard to explain, since I wasn't out looking for the glitch.
