Firefight Descent - Quarantine CE3 2014 Trailer

Firefight: Descent Quarantine is a 2019 Mod for PC (Microsoft Windows) built on Halo: Combat Evolved, shifting the core shooter experience into a high-stakes survival scenario. You are deployed into a quarantined zone to investigate a failed mission, facing escalating waves of enemies. Its unique feature is the introduction of a vicious, rarely seen adversary that significantly heightens the tactical challenge over standard firefights. As a community-driven modification, its value rests entirely on this intense, focused combat loop.
