Just another quiet day in the old harbor—until hell shows up again, as it apparently does. A tower-shaped temple is being built in the murky water district to serve as a place of worship for hell gods and, less ceremonially, as a slipgate for infernal forces. As a member of C.A.H.I.G.O.—the City Anti Hell Invasion Guardians Organization—you are tasked with infiltrating and destroying it. The direct routes are sealed. The only way in is through the underground flood channels that surface in the old town of New Venice, where the temple's hidden entrance waits.
