Containment Facilities

Halo was built to study and contain the Flood infection. To do this, the builders created prison-like containment factilities to house the infection and keep it from escaping to find viable sources of food.

Captain Jacob Keyes folowed a team of Covenant to find the weapons cache and in the research he endend in one containment facility, there he was atacked by a wave of Infection Forms, his team did not survived. Only Sergeant Avery J. Jonhson survived thanks to his Boren's Syndrome.
