Story Synopsis
Four second-generation survivors adrift on the boundless sea intercept a mysterious distress signal out of nowhere. Clinging to a glimmer of hope, they alter their course and head for the coordinates marked by the transmission, sailing straight into an endless, eternal fog that blankets the entire ocean.
At the fog’s heart lies an isolated island. A peaceful, idyllic small town stands upon it, seemingly a rare safe haven amid catastrophe — yet it is nothing more than an elaborate, man-made deception. Deep beneath the town rests a massive research facility sealed away with forbidden, runaway experiments. Mutated infected roam every corridor, with lethal dangers lurking around every corner.
The four fight their way through countless blockades and push grimly toward the facility’s core. Only a submarine dormant deep on the seabed offers their last chance to break free from this prison of despair and return to the open ocean.
Developer Notes
This campaign consists of three map chapters. This is my very first custom map project, so the overall polish is quite rough. I ask for your understanding. Please report any bugs or glitches in the comment section.
