I have few questions about how you gain credits/XP in Halo reach and 4.

  • How is the amount of credits in Halo Reach calculated after you have played a game? What ways can you earn credits in each game mode (Campaign, Firefight and Multiplayer)? Which different actions give credits and how does you get credit bonuses? Is it a max amount of credits you can earn per day and how much? How much credits gives challenges and commendations. - It is the same question in Halo 4. How is the amount of XP calculated and which different actions gives XP?

In Reach, you can get credit jackpots (3,000 cR - 5,000 cR) by staying in the same playlist for around 5-10 games.
In Halo 4, just play Spartan-Ops MP for a lot of XP.
