Description

Fetid Marsh extends to K4, K5, K6, L4, L5 and L6. It can be entered either through small cave in Port Crag at J5, by parking your jet ski at J6 or through the Basalt Cave near Nexus of Technology at L7 and destroying a breakable wall. The marsh is swarming with all types of sea serpents, locusts, crabs and siphoners, making it one of the most hostile areas in the whole Black Sea.
