No friends? No matchmaking in Firefight? That's too bad. It's your firefight. No one has the right to hold you back from finding players if you don't want them to. So what do ya do? First, you post here, then, you give a brief snippet of text describing why you think three complete strangers would feel safe knowing you've got their back against the relentless covenant war machine, then, you play some good ol' wholesome legendary Halo 3 campaign together. All Of It. Over and Over. Every week. Till the Sept. Then, you get outta there!
Me? I'm cool. Me and mine go way back. We're set.
