Outbreak Protocol: Tulsa Lockdown

When three experimental viral strains escaped from a private biotech subsidiary operating under Tulsa’s oil redevelopment program, the city was sealed off within 72 hours. The government calls it a rabies mutation. Helix Dominion calls it an “unfortunate incident.” The survivors call it Nightfall. Tulsa is now a quarantined zone of skyscrapers, burning refineries, farmland enclaves, armed militias, and infected that evolve after sunset. Some people are immune. A rare few are something more. And someone is trying to uncover the truth.
