[quote][b]Posted by:[/b] Go Vader 1. I wouldn't consider it a point to be honest. They were contained, but broke out. If that happened on Reach, it would be far worse.[/quote] Think about this. Because of the breakout, ONI would have to look for a stronger containment location. This rules out most if not all containment facilities on remote locations, where a breakout has a high chance of happening. Now they discover alien ruins with technology far beyond what the humans ever had. And even better, they can reverse engineer some of it! (the super strong alloy the Forerunners love using, the shield technology that could have played a part in the development of the Mjolnir armor, etc). The humans even discover these "Forerunners" had encountered the Flood before, and installed containment procedures on every major installation that was built, regardless if it contained Flood (that is the smart thing to do, is it not?). This new shield technology that resembles the covenant's shields but is far superior requires a lot of energy, energy only the forerunner facility on Reach can provide. It is a risk vs. reward kind of thing. ONI knew humans were losing the war, it was either experiment with the Flood and have a chance of discovering something that can be used against the Covenant, or face eventual complete extinction. [quote]2. If you have the Flood contained to one room...isn't that something of a containment chamber lol?[/quote] Oh, no, you were referring to a facility that was specifically designed to contain Flood. Maybe the humans repurposed some of the Forerunner technology (as well as the backup containment procedures) and created a pseudo containment center.
