Credits

Credits (usually seen abbreviated at "CR") are a unit of money used throughout the Galaxy. Obtainable by the player for completing matches in any game mode, they can be used to purchase new character customization options such as armor or weapons, or for buying ammunition and items in the campaign mode.

Credit Earning
Depending on mode and difficulty, credits can be paid out in large quantities or barely any. Completing a campaign level on the "Novice" difficulty will only earn the player 1,000CR, and every kill within the campaign is worth 1CR with a 1x multiplier. Playing it on "Suicide", however, earns the player a 10,000CR for completion and 1CR per kill with a 5x multiplier. Dying too many times will lower the end multiplier. Performing certain actions, such as getting ten kills without dying, will award a small bonus as well.

In multiplayer, credits are awarded at the end of the match based on metrics such as whether or not the player's team won or lost, what place the player was in and the ratio of kills to deaths. Again, some bonus credits can be awarded for making consecutive kills without dying, using a variety of weapons and vehicles or scoring objectives in certain gametypes.
