Killbots

Killbots are one of the oldest, if not the oldest, NPCs on Roblox. Back in December 2006, the early Roblox developer Shedletsky coded a model of a floating robotic sphere, which shoots an explosive projectile at the nearest living character in a level. The Killbot was originally uploaded to the Roblox website on January 25, 2007, but was featured in several games before this date.

Notable Appearances

 * Trouble in the Killbot Factory (January 1, 2007)
 * Classic: Glass Houses (February 16, 2007)
 * Timmy and the Killbots (April 18, 2007)

Trouble in the Killbot Factory
Little is known about it's appearance in this level, except that the Killbots in this level were a violet color, and coded similarly to the January 25, 2007 model. The level's appearance itself was similar to Timmy and the Killbots.

Classic: Glass Houses
In this appearance, all three main varieties of the Killbot are shown. In the beginning of a round in Classic: Glass Houses, a yellow Killbot spawns above a cage structure in the center of the map. It then proceeds to shoot rockets at the nearest humanoid and fly towards important areas of the map, such as turrets. But, this isn't usually a huge problem, as in this appearance, the Killbot can be destroyed instantly with the touch of almost any projectile. What is a huge problem is that each team can spawn their own Killbots, which will only target humanoids on the opposite team.

Timmy and the Killbots
In a dystopian future, Robloxia is overrun by killbots. In this appearance, yellow Killbots spawn every second in random locations, causing chaos with ease. The chaotic nature of this level kept it (somewhat) popular until 2011. Surprisingly, the level only amassed 93,000 visits.
