Built by a resurrected Dr. Proton during his takeover of Area 51, the Bomb Balls are designed to overwhelm an enemy with sheer numbers and detonate themselves on him. With the ability to hover, they keep themselves at a distance and hover all around their target in an attempt to disorient him until they are primed, at which point all Bomb Balls rush toward their target and explode, with fatal results.
Commonly traveling in large packs, Bomb Balls flash a red light if they are in passive patrol mode. If they are primed for detonation and ready to attack, they flash an array of various colors before rushing headlong into their target.
Eventually, all creations of Dr. Proton, including his Bomb Balls, were destroyed at Area 51 when Duke Nukem killed Proton and destroyed a portion of Area 51 before escaping with his friends, General Graves and Dylan.
- In Duke Nukem 3D, the Sentry Drones behaved very similarly to the Bomb Balls and may have been the inspiration for their design.
