Want to beat this boss in under 10 seconds?

At the end of Central Processing: Primary Server Bank (once you leave the rotating bridge), you will reach Sabaoth AKA Sergeant Kelly. He's on tank treads much like Mutoid Man from Smash TV.

Sabaoth fires a BFG 9000, but the green projectiles can be destroyed with bullets from something like a chaingun. However, the classic-styled strategy of destroying these projectiles and running circles around the room whilst dodging behind columns in not necessary.

The easy method to defeat Sabaoth is simply the Soul Cube. Have the Soul Cube charged from 5 demon-deaths and then hold onto it for this boss fight. Once the boss fight starts, fire an entire clip of chaingun ammo into Sabaoth for insurance that he will die. Be sure to direct some of that gunfire into any BFG blasts he may launch at you. Then launch the Soul Cube directly into him. He will instantly die causing a cutscene and the achievement to pop for 15G.

I believe Sabaoth takes 2 Soul Cube hits to die, so the chaingun beforehand makes sure he's weakened enough to die from the Soul Cube. There's no other enemies to kill during the boss fight to recharge the Soul Cube, so make sure it's charged before you start.
