How to get fast Halo 3 experience. Let me tell you how but first let me tell you its pretty pointless, spend all that monotonous time on just a number, trust me its monotonous.
But here are some ways to do it, All in double XP weekends! Griffball(or any other 4v4 social), get 4 people and 1 kid with a bad account and 3 other controllers, have him sign in a whole bunch of guests(they automatically will be on the same team) then have him quit right as the game starts, he looses xp, but the other 4 get 2 easy points in like 10 seconds. That requires the 1 throw away account but its fast.
That's pretty much the fastest way to do it, you cant get fast easy xp if its ranked, just social. Like i said don't waste your time on a stupid number but if you really want too.
there is a setting for that
play good

It all depends on preference If you like shoot-em-up, kill as fast and as many as possible, Halo-3 is your game. If you like tactically, slowly taking out your enemies with precision then go with ODST.
A simple answer to that question: Practice.
halo 3 obviously
Halo 3: ODST is the newest of the two, but not the newest Halo game.
The halo time line goes Halo Wars, Halo: Reach, Halo:CE (halo 1), Halo 2, Halo: ODST, Halo 3. Halo 3 and ODST are practically at the same time.
If you're fast pace, it would be 4-5. If you're a Sniper, it would be 3(Default),
After Halo 3 there was halo wars, halo 3 ODST, and Halo reach. A new company (not Bungie) will be making a Halo 4 and rumor has it there will be a remake of Halo Combat Evolved.
