Freddy Kruger has badly scarred skin on his face and sharp, blackened teeth, and has knife blades covering each finger on one hand; Jason Voorhees wears a hockey mask and we can see a bit of hair and a badly malformed head and ears (he carries a huge machete as his weapon of choice).
Many people are carved up, sliced and diced by the two bad guys:
A young man lying in bed is stabbed repeatedly through the back, he groans with every strike (we see from under the mattress the knife poking through and blood and tissue pouring through), the bed is then folded up bending the young man in half backwards (we hear crunching and squishing and see blood pouring from his mouth).

The film features a "dream" world along the presumably "real" one.
Two men fight in the real world, with many punches and kicks: one is dragged along a wall through windows and beams, one is thrown out of the cabin and through a roof, one is knocked through the air by a flying gas tank, one is impaled by falling metal rods (blood pours, spurts and sprays), one is hit repeatedly by a swinging cement conveyor, one is hacked in the back repeatedly, one is stabbed in the eyes and the stomach repeatedly and blood pools on his body, one pulls something out of the other's chest, one pulls the arm off the other (blood pours and sprays), and one falls and dangles by the foot and he is pulled down and cut by the other one. Both are hit by a rolling cart, one's fingers are cut off and he drops his knife, and when the dock they are standing on is set on fire a gas tank explodes and sends them both, in flames, into the water.
Two men fight in the dream world: one has his arms hacked off, they spurt blood, he grows two new arms, one is pinned to a pole by a machete through his chest, they fight with punches and kicks and throwing each other into walls and pipes (one bounces around as if he is in a pinball game) and a huge barrel falls from the ceiling and lands on one of them (he pushes it off and continues fighting).
