Resident Evil's Biggest Cliffhangers and Unresolved Plot Threads

Key summary
Resident Evil is officially 30 years old; Capcom has released over 30 RE titles since 1996, counting spin‑offs and now-defunct multiplayer like Resident Evil Re:Verse.
Most Capcom RE games are story-driven and usually provide definitive endings that wrap up their plots (often via explosions).
Still, the series has continuity issues, plot holes, and unresolved cliffhangers; some questions get answered while others remain unanswered for decades.
Resident Evil Zero introduces escaped convict Billy Coen; Rebecca Chambers takes his dogtags and says she will fake his death to give him freedom, yet Billy never appears again.
The woods around Raccoon City are shown to contain zombie dogs and other threats — this summary contains MASSIVE SPOILERS for the franchise.
