1v1 vs. melee bots

Where to get robot JARs
To use a robot, you must download the robot's .jar file (all robots come as ".jar" files, which means "Java ARchive").
Robot JARs can be found in the following places (in order of preference):
- The download link in the robot's bot page.
- The RoboRumble bot archive (or its GitHub mirror).
- The URL in the RoboRumble participants list.
Where to put robot JARs
Robot JARs should be placed in the
robocode/robots/ folder, for Robocode to load them.
Optionally, you may use the Robot -> Import downloaded robot tool to copy JARs into that folder from another location.
