Special thanks to botman for spawning the Half-Life bot craze, and Pierre-Marie Baty for his work continuing the HPB bot template!

Half-Life Deathmatch
These shots are taken from Datacore, the only fully waypointed map as of this writing. I executed a CFG to spawn some bots and just quickly ran around to find one so I could capture a few images. The red beams are indicators of the bot's current goal waypoint; the green beams are the bot's current waypoint; the vertical white beams are waypoints while the horizontal white beams are waypoint paths.
These images were added on Saturday, October 23rd, 2004. They are the results of 10+ hours of continuous combat by the bots in HLDM, as a stability test. Note the console in the second two screenshots, proof of the uptime.
Now, to show off the Science and Industry support. Currently there are two levels I have waypointed, my own simple test level for the bots, and si_overtime. These shots are snapped from si_overtime. All the beam colors from Half-Life Deathmatch are the same here, waypoint display was not turned on.
