Worms have a reputation of being gentle critters that never hurt anyone. At least that how it was before they turned in to blood-sucking, brain eating zombie-worms. Now, you're stuck in the sewer and you have to get out, but in order to do that you have to hack'n slash'n shoot your way out. Use the arrow keys to move around. Use the mouse to shoot, and use the left arrow to swing your sword. There is only one way out, and it's right through all the zombified worms.
