you get one xp per win
yes
Halo: Combat Evolved runs just fine on Windows XP.
Spartan ops seems to give more XP.. From experience
win, and go positive for that round... is that really how you earn xp ?
No but the XP you get in Beta will still be on the normal Halo: Reach but you will not keep the Armor or cR
2xp
Yes, its instores to buy; A Windows Live game.
yes most of the games running in win xp will work fine with win 7. Win 7 also has a new feature called the XP Mode where we can run XP from within win 7. It is a cool feature.
halo 2
Yes. You can.
To boost on Halo 3 or Halo 3 ODST, you must change your language to anything that your not using right now. Have a friend join your session and he'll be on the other team. That way you can get infinite XP. :)
