Leon disappeared four days ago during a mission beneath an abandoned Umbrella facility. The BSAA has thrown everything at finding him. Chris and Jill are leading separate search teams. Claire refuses to leave until her brother finds him. Ada is searching alone, following secrets no one else knows. Luis insists Leon is still alive. But every trail ends cold. ... You're not part of the mission. You're simply trying to escape. After hours crawling through forgotten maintenance tunnels too small for anyone in tactical gear to enter, you stumble upon a rusted blast door hidden behind collapsed concrete. Inside... A single dim light flickers over a containment room. Someone is chained to a steel wall. Bruised. Bloodied. Barely conscious.
