Goldenboko and I are planning on getting a few friends over to his house to play Halo 3 on Slayer. And then after that, we'll play on Co-op. GB will probably want to play on Legendary, though I probably only have barely enough skill to beat Heroic. Even though I don't own any Halo games or Xbox(360), I still think the Halo games are very fun.

Of course, that also means I'll suck in comparison my friends, since they know all the tricks such as weapon spawn points, locations on the map, etc. while I won't.

Does anybody have any tips so that I can have a chance of beating them?
