The number of Mogs running down the dark tunnel is staggering; and with the flashing lights and piercing sirens, it’s a sensory overload. Sam pulls both triggers and mows down row after row of Mogs, but they keep coming. When he’s out of bullets, Sam grabs two more guns.

“I could use some help here!” Sam yells, mowing down another line of Mogs.

“I’m thinking, I’m thinking!” The mucus-covered walls of the tunnel don’t appear to lend themselves to spreading a decent fire, and I don’t have enough of the green lava in my hands to do enough damage. To my left are the silver gas tanks and silos with their heavy pipes, spouts and aluminum ducts. Next to the tallest of the silos I eye the control panel with electrical wires pouring out. I can hear the screams and roars of the beasts in the barred chambers farther down the hall, and wonder how hungry they are.

I toss a flaming ball at the control panel and it disintegrates in a storm of sparks. The bars of the chambers lining the walls begin to rise, and that’s when I toss the other green ball at the base of the gas tanks and silos.

I grab hold of Sam and sprint with him back into the giant’s chamber. As the explosion erupts, I whip Sam against the stone section between the wooden door and the rising steel gate, and allow the advancing wave of flames to sweep over me. My ears are flooded with the crackle and hum of fire.

Dozens of krauls burst from their open chamber and attack a series of unsuspecting Mogs from behind; several pikens stomp into the tunnel with roars and swinging arms; the reptilian mutant with horns charges towards the back of the tunnel, plowing over Mogs and krauls under the legs of the pikens; the gargoylelike winged creatures buzz at the ceiling, swooping down to take a bite out of anything they can; and the monster with transparent skin sinks its rows of teeth into the calf of a piken. That all happens in a matter of seconds, then they’re overtaken by a sea of fire.

After a few minutes, once the fire escapes up the spiral cavern at the end of the tunnel to continue to wreak havoc throughout the mountain, the long corridor in front of me is littered with ash piles and black monster bones. I extinguish the fire surrounding me and brush my hands off onto my thighs.

Sam is singed, but otherwise okay.

“Brilliant, dude,” he says.

“Let’s just try to get the hell out of here, and then we can celebrate.”
