[quote name='DarthPuma']Hey Rocko, just FYI if you do buy Halo 3, I'm pretty sure they're making the Map Packs mandatory for everything but the social playlists. I'll have to check to make sure, but if they are that's another 18 bucks you have to spend on the game.[/QUOTE]
Where did you come up with $18? The map packs cost $10 each. $10 + $10 = $20?
But yeah , without the Legendary and Mythic Maps , the only modes you'll be able to play are:
Ranked - Lone Wolf , Squad Battle , MLG
Social - Social Slayer and Social Skirmish
That might not be all , but I think that's most of it.
