You, the Doom Marine has been sent to the depths of Hell after discovering a whole civilization of demons of all sorts in the under world. Your objective is to slaughter every demon who would dare to stare you down, or even oppose you.

All the demons and sinners of Hell are living about their daily scumish lives with buildings either crashing down or set a light... That's when a blue portal opens up, ripping apart a Succubi for standing in the way of said portal.

Sinners/demons around are in a state of confusion as the portal opens. That's when a bulky, armoured marine steps out and crushes the Succubi's remaining skull with the sole of their boot. The marine is grasping onto their Super Shotgun, cocking the gun menacingly while looking around at the city before them...

[Remember, Slayer; Rip and tear, until is it done.]
