Briefing

The latest production run of R-109 prototypes is being combat tested. The most lethal unit will be awarded with a command firmware upgrade. Demonstrate that you are the best.

Strategy

Grab a Homing Launcher and start blasting away, you have to reach 40 kills for a Gold. Surprisingly, a great place to stick around is around the main building, as the R-109 units come a blasting, run around them in a circular pattern and blast them away. Since every other R-109 robot has a Rocket Launcher, or worse, a Homing Launcher, you have to be careful about where all of the other robots are.
