With the true horror of the Vault’s contents now revealed, the lone survivors must reach the decrepit platform of Fathom South, their one chance at contacting the surface, not just for a rescue, but to contain the dangerous technological contagion that is quickly spreading through what remains of the underwater base. To do so, they will have to find a way to repower and drain the platform, as well as navigate its infected corridors and tunnels. With time yet again running out, they turn to Dr. Eva Graff for help. Trapped inside what’s left of the slowly flooding platform, she poses a dark, sobering question: Will calling for help lead to their rescue...or doom the entire planet?
