Play online. Online games provide more opportunities to complete online challenges and earn online commendations than campaigns do. You will also earn credits more quickly online. For example, earning a headshot against another player will earn you 7 credits, rather than the 4 credits you earn for a headshot against a non-human opponent in the campaign.
Play matches in Firefight game mode. Firefight allows players to play with friends and quickly kill CPU enemies and win games. On average, a firefight game can last six to ten minutes, with players averaging 900 to 1,200 credits per game. Since Firefight has several game variants within each playlist, players should vote and play either Rocketfight or FRGfight; these types use heavy weapons, and games are completed much quicker.
Earn your commendations. As you play each game mode --- Campaign, Matchmaking or Firefight --- you will earn commendations for earning a number of headshots, long-ranged weapon kills, assisted kills and grenade kills. Each earned commendation will accrue credits and help you rank up more quickly.
Complete your daily and weekly challenges. Daily challenges allow players to earn more credits for completing certain objectives each day, while weekly challenges typically require players to play throughout the week.
Play and complete as many games as possible. Players earn game completion credits for each online multiplayer match they successful finish, whether it is Firefight or Matchmaking. Each game provides a player the opportunity to earn credits and stats that go to earning commendations. The more games you play and finish, the more quickly you will rank up.
