Super Sewer

In one of Humanity's biggest sewer systems, lays a perfect under-ground advantage to assault the opposing team. Unfortunately, so much waste is trapped here that water often backs up. The Zombies, finding out about this first, set out to weaponize it for strategic gains, but the Noobs just so happened to find out from a Nafty Noob spotting the forces moving in. Now, both factions fight for control of the Sewer to make it into a stronghold for their own. However, some remaining Humans won't let that happen. Some soldiers and warriors complain about the horrid smell, but are forced to fight anyways.
