Infectious, Isolation's Floody secret

Before Halo 3's launch, IGN previewed multiplayer map Isolation and talked with multiplayer lead Tyson Green who hinted at a special "feature" that Isolation reveals after playing on it for a while. Well friends, the secret is out and it's a subtle change. The Chief over at the 7th Columnist forums discovered the Isolation secret where after you play for a bit, the Flood infects the rest of the map making the ground all spotted and icky. It doesn't affect gameplay in the least and some may not notice it (we surely didn't), but it's still something rather nifty that you can point out to your friends. Yup, it's the little things in life.
